I have the education version of Solidworks and it has been working properly since the beginning of fall semester, but recently I have been having a lot of problems with the program. When I try to open any of my part files I get an error message saying that my access was denied. When I create new parts, I can't save them because I get an error message. I attached the error message I get when I try to open a part file and I put my device specifications below. Has anyone seen this problem and figured out how to fix it?
