iTunes has experienced a problem....

Now everytime since then, it says it has 'experienced a problem and has to close.

if you're getting that on launch (of itunes), that's usually a problem with a broken or missing QuickTime (itunes needs a functioning QuickTime in order to work properly). but there's some rarer things that can cause it.

with an eye to working out which causes you're having, can you try launching your QuickTime for me?

does it launch properly, or does it behave oddly?

if you get an error message (with the QT), let us know what it says. include error message numbers if you're getting any.

okay, if you're getting that error message when launching itunes, but your QuickTime is launching fine, it's plausible that you've got a damaged itunes preferences file.

if that's what is going on, we can usually get past it by "rebuilding" the itunes preference files. for the rebuilding technique, see the following user tip (it's on a different topic, but the preference file rebuild technique is the same).

b noir: iTunes won't let me change a preference

🙂 i'm going to take that as a good sign. glad you're up and running again, Mandi.
