Apple Logic Pro /LogicExpress Discussion

Hi All,
I am running OS 10.3.9, Logic 7.1 on a dual 1.8 G5. Lots 2.5 gigs ram.
On only one of my project I get a crash message (like the subject says) when I attempt to 
open it. It loads all the plug-ins then crashes. The last thing I was doing in the project was 
editing a EXS instrument.
Can anyone help me get this back open/

Thanks in advance...
