trouble sharing w/ a colleague

[joedoc8804]

I've been working on a series of documents w/ a colleague.  Everytime I send him something I did we have no problems.  Every time he sends me something he worked on and I try and open it, it shuts down my visio.  Does anyone have any suggestions?

same versions of Visio?
Drawings in same formats (VSD vs VSDX)?
Any templates in play / VBA enabled or used in one but not the other?

No we actually used the same templates from the same source and we work at a college so ostensibly I'd imagine they'd be the same on the school laptops.

try a drawing with just 1 square....back and forth.....note what happens
