Soundtrack Pro 2 keeps crashing...please somebody help :(

Question

So here's my problem.
I am running Soundtrack Pro 2 on my Mac Pro along with my Digi003. Both Final Cut Studio 2 and Logic Studio 8 are installed on my computer. Every application works fine except for STP2 that keeps crashing all the time.
I tried to uninstall it, reinstall it, reinstall Compressor, downloaded updates, Core Audio updates as well for the 003, downloaded the last Pro Applications Support but nothing seems to cut it.
The issue is as follow. I launch STP, the application scans (for the hundredth time) my plugins and detects something like 287 plugins. HOWEVER, the application crashes when the counter goes to 290.
My personal feeling is that the problem might come from either a conflict between Final Cut Studio 2 and Logic Studio 8 that installed both STP2 or, most likely, three plugins (the difference between 290 and 287) that STP2 has a problem with.
These last plugins scanned seem to be Amplitube X-Gear, a demo I deleted, Melodyne, that I downloaded lately and I guess something else. Also, I precise that I have not been able to rn STP for almost a year and as I am about to work on the post of a new film, I would love to use it.
The last thing I did was running the Terminal app that gave me a detailed report of the problem. I don't understand where it comes from though. So here's the report. If somebody can help, I greatly appreciate it!

Answer 1

Probably an imcompatible plug-in.
Try renaming the plug-in folder momentarily, see if it boots okay.
If it does then you'll have to isolate which plug-in is causing the problem.
