Hi, my AutoCAD cant open anymore at all, just says Application not Responding. It used to be able to launch the startup screen at least but now it cant do that either. This has come out of nowhere as its been working fine the last two years and I havent updated it or my computer in the last few weeks that could have caused this. Wouldnt be surprised if its my computer giving up, but any help at all would be great!

Im running AutoCAD 2014 [Student Version] on Mac OS X, have tried uninstalling and reinstalling but no luck
