Thread: iPhoto (Preview) not working!

Hello everyone, I installed iAtkos S3 V2 on my pc and everything works fine but when I open a picture using iPhoto (Preview) is shown only gray background, is also not working screenshot, when I make a screenshot (using Command-Shift-3) hear only the sound but on my desktop isn't saved files.
The same case is with Photoshop don't display a gray background, but there are hole, the field is transparent that I see the desktop background.
I should note that iPhoto and the screenshot option works in the past, when the system was freshly installed.
Does anyone know how could I fix this problem?
Sorry for my english.

the iphoto problem could be that the database needs to be rebuild
