DVDsp won't let me create a DVD

I've been using DVDsp for several years now and it has always worked fine. But now, whenever I click "Burn", "Build", "Format", or "Build/Format" the software crashes.
I've trashed the plist and that didn't help, and I have no idea what else to do. I'm facing a deadline, so I need to figure this out in the next few days. Any suggestions will be very helpful.


The other problem might be that you need about 20 MB of free space before you can burn a DVD - DVD burning takes lots of resources. Delete any files you can so free up space on your HS. Also, I usually create my project, save it, restart and then burn to DVD.
