16. Troubleshooting
| Problem | Solution |
|---|---|
| The sign-in screen does not go away | Read its title (§3.2). Most often you need to finish signing in in the browser or get a license on the account page |
| "Every slot on the licence is taken" | Request a slot for the device on the account page or free a slot through support |
| "The offline period is over" | Connect to the internet; work resumes after the server responds. Check whether the clock was turned back |
| The map tree is empty, there are no catalogs | File → Map catalogues… (Ctrl+Shift+K) → download. Catalogs are not part of the installer |
| "The block was recognised, but access to the catalogue is not open" | Open the purchase catalogue; after payment — Check access or wait for the "Access granted" banner (§4.5) |
| Paid, but access has not appeared | In the "Map catalogues" window press Refresh the list — access appears within a minute of payment |
| The "Not mounted" status | The reason is in the right-hand panel of the "Map catalogues" window; More ▾ → Retry download (§4.7) |
| "The catalogues on this computer no longer open" / "Setup needed" | The system has changed; the computer has to be registered again through support (§3.4). Downloading again is pointless |
| "The catalogue file is damaged" | Download again; the program did not change the file, the license is unaffected |
| "The catalogue was built for a newer version of TCEPro" | Help → Check for updates… (§15) |
| "Could not download catalogues (N): …" | Check the network; Retry download. The previous copies are unchanged |
| "Access to the catalogue could not be checked" | No connection to the server. Check again or Work offline |
| "The block was not found in any catalogue" | Request support for this block; check the "Identity" panel |
| The maps came from the wrong catalog | Status bar → "Catalogue: …" → Open from another catalogue…; to reset a remembered choice — Remembered choices… (§4.4) |
| "Access to the catalogue … has been revoked. The map windows of that catalogue will be closed" | Press Save the project and close; then contact support |
| "This computer's key does not match the licence server's key" | Contact support — this cannot be fixed on your own |
| A catalog downloads for a long time / the traffic is metered | Cancel download and switch off "Download and update catalogues automatically" in the settings (§14.1) |
| A catalog has the "Disabled" status | You disabled it yourself: Enable in the "Map catalogues" window (§4.2) |
| "A new version of catalogue "…", which you are working with, has been downloaded" | Save your work and restart the program — the new version opens |
| There is no "Export Firmware…" item | Contact the supplier |
| "Overwriting the source file is forbidden" | Choose another path |
| "Failed to recalculate checksums, the file was not saved" | The file was not written; tell the supplier the unit family (the "Identity" panel → Copy all) |
| The question "Recalculate checksums and RSA before writing the file?" on every export | That is the default; choose "Automatically" or "Do not recalculate" in the settings (§14.1) |
| "The preset of this block's family sets no checksum recalculation method" | Recalculation is not supported for this family (§12.1). Save without recalculation only if you understand the consequences |
| The "Shared axis" dialog | The axis is shared by several maps; No writes nothing, Yes changes the axis in all the listed maps (§8.4) |
| An empty table after selecting a map | Wait for "Parsing map…" |
| "Could not open the map "…": it parsed, and there is no map data" | A catalog defect — report to the supplier |
| "Restore Selection to Baseline" is unavailable | Changed data cells are needed; not smoothing; not comparison (§8.8) |
| "Baseline Chart" is unavailable | No differences from the original, or the map does not support it (§11.5) |
| A chart without colors | Settings → heatmap "No heatmap on charts" |
| Search by value: no results | Check the syntax (§10) |
| The project did not open | The error text names the cause (§5.1); on "Firmware file not found" the file must be next to the project |
| A panel disappeared or came off the window | View → Reset Panel Layout (§11.4) |
| At start — a message with a code, for example "The environment protection check failed… Code: SEC-PROTECTION" | Start the program again. If the message repeats, contact support and give the code |
| "The text of the licence agreement was not found next to the program…" | The program files are incomplete — download and install the program again |
| Linux: signing in does not work or is not kept | Make sure the desktop keyring (GNOME Keyring or KWallet) is running and unlocked (§2.1) |
| "TCEPro is already running … is not responding" | Switch to the window that is already open; if it has frozen — close it through Task Manager and start again |
| "Internal error. An internal error occurred, the action was not completed" | Save your work and restart the program; details are in the log (%LOCALAPPDATA%\TCEPro\logs\) |
