Hi,

I have Solidworks 2014, and have a Dropbox with 50-odd drawings in it. 

We replaced the PC at the start of the year and installed the same version of Solidworks on the new one.

Problem is we cannot open any drawings that were created on the old PC, we get the "there was an error opening your file" message. (in both SW and eDrawings)

New drawings made on the new PC save and re-open fine.

Any ideas where to start?
