problem opening a project
 

I have PP1 (actually, I just got 2.0 but the project in question was done on the earlier version). When I try to open a wedding project I've been working on I get a message saying the project has damaged or outdated elements.

I've put a lot into this project over the last few days. I tried opening one of the saved backup versions but they are all giving me the same message.

Any thoughts on how I may be able to open this project? Any input is appreciated.
