Drawing not opening

Hi, I've got a drawing in SW2012 that I was working on yesterday with no problems, but today will not open.  SW just freezes and won't let me click on anything. I am able to open it on a coworker's computer, and I noticed that my computer updated itself overnight, and his did not, so my guess is that it has something to do with that.  Any help is appreciated.

PS - The drawing is 28MB and consists of exploded views of my 29MB model, which opens fine.
