First I get this screeen.

Then when I hit continue I get this screen

I tried to get it to create a report but no luck.  Any ideas what might be going on?

I get this same error when i quit.  but it is random - it does not happen all the time even with the same project.  MC 3.0.1 is very buggy for me.

I can't read the error in your screen grab, but I think it's the Assertion Line 629 error. I get this too -- consistently when I quit with a sequence loaded. I have not figured out the cause, but I did notice it stopped with a clean install of MC on a partition with a clean install of the Mac OS.

I posted about this error earlier - here's the thread:

I'm getting his error in MC v2.8.4 on some projects.  

I got this message also. It happened right after I applied a BCC5 blur effect on video 2 and than tried to option drag a resize effect on top of the BCC blur effect. POOF! had to restart and lost the past five minutes of editing.

Sounds like some bad juju from this Tiger system.  If I had time to reinstall the entire drive I would, but I don't.  Hopefully we will get the firewire fix for Leopard soon and I can use my Adrenaline on my Leopard drive.
