Hi xaos29,
If your iTunes application is unresponsive, you should first make a backup of your iTunes library, or ensure your Time Machine has backed up your computer, then uninstall iTunes. Restart the computer and make sure there are no other issues with the computer (ie login items, etc.) before reinstalling the iTunes application. The resources below provide other avenues to troubleshoot this issue:
