iphoto wont work
I accidentally deleted iPhoto, but when I installed it back on, it says everytime that "You can’t open your current photo library using this version of iPhoto." I have tried updating, but it didn't help, how do I do this? and because of this pop-up window I cannot find out exactly which version I have installed with my iLife '09, but obviously the 9.1 update wouldnt work. HELP!
Mac Pro, Mac OS X (10.6.8)
