We have recently got the following error message on my laptop. Can you tell me what we can do to solve the problem?


Maybe the user-defined cross-section library EigProf.dat on your computer is missing or it is corrupted. Please open the "Data Files" tab of the program options and select the "User-Defined Cross‑Section Library" category.

Open the displayed directory and check whether the EigProf.dat file is available. If the file is available, please rename it.


If the path including the file in the program options does not correspond to the default path for RFEM 5.xx "C: \ ProgramData \ Dlubal \ RFEM 5.xx \ General Data \ EigProf.dat", set this default path in the program options.


Error EigProf.dat User-defined cross-section library
