When I import into iTunes, my computer crashes. Help!

I just got a new computer and I just finished transferring all my media to the new computer (btw, it's Vista...yeah.) . I exported the XML file from my other computer and changed the file location to match the new locations. When I imported that XML file, it starts importing...then it locks up. I tried it again, but it worked, but I had to send that computer back b/c it had an error.

I got a NEW new computer (just sent that computer back) and I did it again, but it crashed. How do I import it without crashing? :confused:
