The Newbie Nightmare
Now this is wierd. There are 5 user accounts on my computer. After installing Service Pack 2 for Windows XP, QuickTime (and Media Player Classic) now only work on one account (my account), but won't function at all on the other 4 (all user accounts have administrator privileges). Media Player Classic will start up abd then immediately shut down again, whilst QuickTime won't open whatsoever.
