Hello all respected members,
Have you ever faced this problem that the Caesar 2018 (ver 10) Input window and graphic window is not opening. However the files that I had run earlier I can open its static load case window and can also run it for analysis. But can not open the input window only.

But to my surprise, I can open the Caesar 2014 (ver 7) input window and can also run it for analysis.

Please suggest, if I need to do some setting change or some other issue?
Regards
