Please try the following first:
- Run RFEM/RSTAB as an administrator by clicking the icon on the right and selecting "Run as Administrator".
- Import the Author.ini file again, then restart the program.
- If this does not work, send me the authorization.txt file that you can create via Help → Authorization → Diagnostics.
