all the issues with Vista were resolved a couple of updates ago. The Auction Wizard tech team got those all fixed right off the bat.
As far as your new computer--Congratulations!!!
You can download AW2000 onto your new computer, pop in a backup disk that contains all your current data, hit "restore database" select the drive your disk is in and let AW2000 work. All the database will be restored to the new computer in just a few minutes.
Then run AW2000 and check through everything to be sure it is correct. But I have yet to ever have a restore not work correctly. And I use restore a lot at the college. I am forever making up fake databases and moving them from computer to computer. Same principle so it will work just fine.
Does that help??
