It won't open, at all, I've deleted every plist associated with iTunes, the cache, everything. It will only open if I do it manually through Terminal, and that isn't perfect in my opinion. Is anyone else experiencing this? Edit: I have also downloaded it twice and installed it twice, same thing happens. Edit 2: They've pulled iTunes 10 from the download page. lol And it's back. I wonder if they've fixed it. - Nope.
