Audacity Quit Unexpectedly (Crashes on Bootup)[SOLVED]

Hi,

I have been using Audacity for a long time. Recently whenever I try to boot it up I get a “Audacity quit unexpectedly.” message. I downloaded the newest version and got the same message. I am trying to run Audacity version 2.0.3 on my Mac OS X version 10.6.8. Here is the full error message. Any help appreciated!

Line 13 shows that Audacity was trying to load an Audio Units effect.
Lines 2 through 9 show that it is trying to load “com.digitech.au.re250”. Do you have an “RE250” (or similarly-named) Audio Units effect on your system?

Oh yeah. Weird. The digitech RP250 is an effects pedal I sometimes use with garageband. I’ve never actually used it with Audacity. So is it trying to load the pedal but fails because the pedal’s not plugged in? Is there a way I can have it forget about the rp250?

I tried removing all the plugins, I followed the instructions on the link you posted. It didn’t help at all unfortunately

I figured it out. i removed all the rp files from my /library/audio/plugins/components
folder. thanks
