A few to many times every single flippin' day, Solidworks 2015 SP 5.0 will NOT open solidworks files.  Not drawings, not assemblies, not parts, no matter what you do, nor how you attempt to open a file.  I dunno about you, but I need to open and manipulate files to get work done.

Does anybody else have this issue?  At least two of us here do.  Is there a fix aside from new program or new job?

I would not be surprised if it was, at least in part, due to the Commodore64 that is functioning as the local server (not literally, though it seems so).
