Okay, this is NOT the typical incompatible version error message that our office is experiencing. We are running (3) versions of AutoCAD ... 2010, 2013, and 2014. ALL, I'll repeat that, ALL, are saving down to 2010. Recently we have been getting errors when opening files on the systems running 2010 that the file being opened (or an xref within a dwg) is an incompatible version. Again, being that ALL machines are saving down to 2010, how is this possible?
We have also audited each of those files and found no errors within them, so I don't even think its a corruption issue.
This is driving us nuts! Is there anything else I should be looking at being the problem? Or any idea as to what the problem may be?
Thank you for any input in advance.
