PT keeps FREEZING when opening session! Help!

[jephreee]

I've been using Protools 6.2.3 on Mac G5, Dual 2GHZ running OS 10.3.9 for several years with no issues, suddenly in the middle of a session yesterday I attempt to print an audiosuite effect on a channel and protools freezes mid-render. Now, the same thing keeps happening when I attempt to open a basic session. FREEZING! EVERY TIME! Tried to experiment with other sessions - the same problem so I know this particular session isn't corrupted.

Even tried to create a new session. Same thing happens! This has been on-going several days now, effectively rendering protools useless and screwing my deadlines.

I can launch pro-tools and my 002 hardware connects without issue, its just using the software to open anything, create anything, or render anything.

Dumped Preferences, Repaired permissions, nothing helps! I really don't want to have to re-install because I'm worried of screwing up my plugins and you all know how much a pain it is to re-install waves (which is why i haven't upgraded OS or PT 7.0 yet).

If someone has encountered this and knows what the heck is going on please help me. Every minute my project deadline is ticking away - can't even open my sessions!

Thank you.
