I need some help with files that my wife edited on her Windows machine using AcdSee. The edited files keep coming up with compatibility errors in preview, won't display in iPhoto and Aperture 2. What's worse is I 'switched' my wife to a Mac over the weekend with the promise of compatibility and stability. She agreed, under duress, so long as the transition would be easy and painless. So far her JPGs aren't compatible and 10.5 has crashed several times....needless to say she's been studying the styrafoam packaging to determine how to put it back in the box and return the iMac....Thus I need a FAST resolution to save egg on my face and keep me from burning one weekend a month cleaning virii and spyware from the XP machine. HELP!
