iTunes "cannot be opened"

[Meldar]

"...because of a problem. Check with the developer to make sure this application works with this version of Mac OS X."

^ That's what I get when I try to open iTunes since updating it. Through Software Update no less.

I am running the latest version of Mac OS X! From looking around the forums here, no one else is having this problem...why's it just me? What'd I do?

...or what can I do? Tried re-installing it. Nope. Tried rebooting, which I usually do after updates. Nope.

Any ideas...?

You must not have looked around too hard ...

(How did you try reinstalling?)

I must have either missed that thread or it didn't come up in search results. Oops.

Tried re-installing from the Apple website. My problem is most likely my ISP, then. See, we can't download large files because of our high packet loss. Oof boy now I sound like a complainer.

Alright, after reading through that thread, I'll try again later. Moving my entire library to reinstall is a pain though. We're talking a little over a hundred gigabytes I need to move back and forth.

Sorry for the useless thread...
