it all started with this: Out of the blue, iTunes won't open. I tried rebooting, repairing permissions, etc. Nothing worked... and I have 2gb of RAM. There's no way that it won't open because there's not enough memory available. So I deleted the app and decided to reinstall it. Now I get this: When I install iTunes again, everything is greyed out in the installer window. This happens both from the iLife 05 CD (4.7.1) and from the downloaded copy from Apple (4.9). Please Help!!
