Stupid crack kept trying to write a .reg file with the serial to the C partition before importing it, and Vista was having no part of that, goddamn new security model. If they had just given me the serial straight up I could've just entered it when asked, instead of having to boot into XP, install it, find out that the program itself has problems with my XP install, run the crack, grab the serial from XP's registry, and then finally boot back into Vista to activate the damn program so it would record more than five minutes at a stretch.
At least I now have a crappy-quality recording of a Belle & Sebastian music video.
