I've recently noticed- some iLife apps are not working. The biggest concern is iPhoto - I've opened up iPhoto '11 (iLife 11) but it says: However, and here's the catch - iDVD, iMovie, working. Just a couple apps are not working (I can't check every single one for compatibility). Is this a universal problem? How do I fix it? I have iLife '10 and '09 if that helps but I haven't checked if they work. Either way, I would like to use iLife '11 over either older versions... Thanks!
