Yep I can open it just fine. I think I got it figured out. I had a custom background image, and once I removed it it opened fine. That is quite strange. I'll have to dig around a bit more and see if there's not more to it because it looked like one of your backgrounds was a custom one as well. Thanks for the help, you'd think there would be a better message other than "file corrupted". Luckily I remembered that there was a custom background in this file (which existed only on the one PC and not the other) and figured why not delete it and see if it'll open.
