Windows 7: "iTunes Has Stopped Working."? (Fault Module: ntdll.dll)

It used to work perfectly, but kept giving me that message every time I attempted to open it. I tried uninstalling and reinstalling everything related to iTunes, but finally resorted to downloading the new version of iTunes, and seeing if that would work. Well of course, it didn't work, so I tried using Repair in the control panel, and repaired QuickTime to play it safe. QuickTime continues to work perfectly, but iTunes has yet to open. It does give me the details though -

How do I fix 'ntdll.dll'? It's not infected or anything.
I've already asked on the Apple forums, with no luck. I really need help with this.

Its not ntdll.dll itself, it was ever iTunes is calling though ntdll.dll. Would need a deeper analysis to determine what.
