I Tunes 8 crashes Vista 64 bit in sleep mode

I just bought a brand new Dell desktop with Vista 64 bit and installed the 64 bit version of I Tunes 8. The program opened, but I was not yet ready to migrate my files to the new PC so I closed the program and left for a while. When I returned and attempted to wake the computer from sleep mode, the monitor started displaying nothing but a pinstripe pattern and the system was frozen, requiring a hard reboot. A second occurrence convinced me to uninstall and do a system restore. Sleep mode then operated properly again. A new install of IT8 produced the same freeze. The program doesn't have to be open when the system goes into sleep mode to cause the crash. I have not even connected my dock to the PC yet. I have over 22,000 songs on my old PC and am very concerned about bringing them over. Is it possible to obtain a workable version of I Tunes 7 for 64 bit? Any help will be appreciated.
