iTunes freezes when trying to close

iTunes (7.6) freezes for me every time i try to close the program. It seems to open up and work fine, however when I click the "x" or go to file, then exit, it freezes up and have to open the task manager and end the process. While it is frozen, the task manager shows it using 100% CPU usage. This is fresh, clean install of Windows XP SP2 with all updates installed. This was happening with the latest version just before 7.6 came out. I did a clean install of XP, installed all updates, installed iTunes and it froze, didn't think much of it.. thought it was just a random one time thing, finished installing all my other programs.. then today i update to 7.6 and go to close it and it happens again! I opened and tried to close it several times and it happened every single time. I uninstalled iTunes (removed old database as well), reinstalled iTunes and still froze. This has never happened to me before and am stumped on how to fix. Any help would be greatly appreciated.
