Project upgrade failed w/9.1?!

[ford347]

I have a project that I just got SD done with in 9.0. I want to upgrade the project to 9.1 since I haven't moved it passed SD yet. I tried opening this in 9.1 and some errors came up stating that some dimension references have become invalid and that geometry could not be joined...but there was nothing to show me, so I don't know what these things are. Then an erorr popped up saying that the upgrade could not be done and I had to contact my service provider. So I will put in a support request, but I was wondering if anybody has had this problem before and if this becomes a serious problem. I have a few projects in limbo right now that I have just finished the SD on, but I need to move forward with them soon, and I want to utilize the new features presented in the release of 9.1, particularly the structural improvements, since this has burnt up so much of my time in the past...! I'm determined to get that back:lol: Anyway, any suggestions would be appreciated.

Thanks
Josh
