The key should work if the registration name and HWID match exactly. A few quick checks:
- Registration name must be exactly kristlarb (lowercase, no spaces).
- Copy the entire license key including the trailing = character. Missing that padding breaks the key.
- Confirm the HWID still reads FF01-C4A2-C050-5C42-71CE-8829-B796-02BA-7A in the app right now. Hardware changes, BIOS updates, or running from a different account can change the HWID and invalidate the key.
- If you updated from 1.0.3 to 1.0.4, uninstall completely, remove the old program folder, then install 1.0.4 clean. Version 1.0.4 must not be installed over 1.0.3.
If all of that matches and it still rejects the key, post a screenshot of the registration window showing the error message and the ECUMaster version number, and I'll sort it out.

Thorough consistency checks can reveal one forgotten map before it affects operation.

A useful cold-start test should answer the important questions at once.

When only one finish line matters, each useful step becomes easier to recognize.
