Difficulty to launch and use SOFIPLUS (-X)

I have some problems regarding the use of SOFIPLUS (-X).
I always receive this message.
Can i have some issues please for this problem ?

Hi Steeve,

please close the project and go to the project folder in your Windows Explorer. Now delete all project related files except the *.dwg and *.sofistik (and if necessary *.dat plus *.gra) files. Please check the screenshot below:

This should help.


I still have this message and i cannot modify the model

I guess the test01.sofistik file is broken.
Delete the files as suggested by A.Freund and open the test01.dwg file directly in SOFiPLUS(-X).
Then open the file test01.sofistik from SOFiPLUS(-X).
