Weird issue with PT and 002

[Carl Fuehrer]

Went into the studio last night to do some work. I am using a Digi 002 on a PM G5 quad with PTLE 8.0.1cs1. I opened a previous mix, it all loaded up but I got the spinning beach ball of death and the 002 had rebooted. Forced quit PT and tried it again, same thing. Forced quit and opened another song mix, same thing. Rebooted the whole system and 002, same thing again. Opened a small writing session and it came right up and worked. What could be going on here?

any other existing sessions doing this?
I'm thinking a corrupt session, try making a new session then importing the problematic one (maybe a few tracks at a time if the whole one is still problematic)
