Final Cut Express 4 Crash due to RP500

What Mac and what Mac OS X version do you use?

Have you installed any audio applications?

Can you show us a screen shot via CMD+SHIFT+4?

Haven't got one of these hooked up have you?

But its not hooked up.

That's a bit of a coincidence. Did the RP150 require the installation of any software (apps, drivers, etc). If so, see if you can find what it was and remove it. If not, stuffed if I know.

Did you try installing FCE?

I think I can help

I hope it's not too late, but the RP150 guitar pedal that you have conflicts directly with Final Cut's Audio Components. Just do this for the fix, navigate to:
Macintosh HD/Library/Audio/Plug-Ins/Components
There you should see that pesky RP150. Don't delete it, just move it out of the components file into the Plug-Ins (or anywhere else) when you want to use Final Cut Express; Then move it back when you want to use the X-Edit program for your RP150.
Good Luck; it took me a while to solve this one because the finder usually doesn't look for .component
