iTunes freezing after latest update 10.6.3
Yesterday, iTunes installed an update to 10.6.3, and since then freezes less than a minute after launch. The beachball just spins and iTunes is completely unresponsive. It is usually downloading a new podcast at the time, but that is simply because that's the first thing iTunes does if I'm not syncing.
I tried restarting.
I tried restarting in Safe Mode.
I tried restarting without anything connected to any ports.
I tried uninstalling iTunes, restarting, installing a new download from apple website, and restarting again.
I'm not sure what to do next....
Everything was working fine up the the moment the upgrade finished.
I'm running a fairly new Macbook Air running OSX 10.7.4 with all software updated.
Thanks for any help!
