I spent hours last night using iMovie and saved everything. Today I come back and there is no IMovie on my machine. I re install the iLife disk and add the iMovie and now it says "You cannot use this version of the application iMovie with this version of Mac OS X." WTH!!!!! Now i'm screwed. Do I need to buy iLife 09???????????? This sucks because I need this project and I can't afford to buy something that is going to be obsolete in a few months. Iphoto and the other apps from iLife 08 are working fine. Any ideas to what is going on?
