Hi, I am usinG PHOENICS 3.6. It was running properly until yesterday. But now when I try to open PHOENİCS VR it gives an error message saying "satexe.exe has encountered a problem and needs to close" and I am not able to run the PHOENICS anymore. What might be the possible cause of this problem and is there something that I can do to fix the problem. Thanks in advance

Try running a standard library case to see if that works, say V401. If that doesn't run, you can try re-installing PHOENICS.
