STPv1.1 crashes every time

STPv1.1 crashes every time I try and open a Soundfile project from within a muli-track project. I can open a soundfile project on it?s own, or open one from inside FCP, mostly. But that sometimes crashes STP too.

Any suggestions?

I?m running
OSX 10.4.10
Dual core 2 ghz Power PC
3.5 gig ram.
FCP 5.1.4
STP 1.1
Pro support 4.0.2
Qt 7
Qt compatibility 1

Trash the preferences!

Thanks, I feel like such a punk.
