iTunes freezes on startup

[Ramener]

When I attempt to launch iTunes, it loads my iTunes library, then stops responding before the iTunes window appears.

Any ideas?

Thanks

It could be a damaged plist file. First, let's try repairing permissions. According to Apple, occasionally the user permissions associated with files or applications become damaged, which can prevent a file or application from working as it should. See this article. So, you might want to try to run Disk Utility (Applications > Utilities > Disk Utility). Open the application, select the mounted volume for your hard drive and click "repair disk permissions."
