Voodoo crashes

I just downloaded Voodoo and am trying to track a shot on a dual Pentium Windows XP machine, but the software crashes about a third of the way into the shot with no explanation. Any ideas about what I should look at to figure out what’s causing this?

The shot is a Targa image sequence, but, depending on the tracking control settings, it doesn’t always crash on the same frame, so I don’t think it’s an issue with the source files.

i did get some random crashes with it too maybe it’s a memory problem …

I have 2 gb of memory. That should be enough, right?
