I cant download any apps from the appstore or update existing apps. When i click the "get" button it turns green and I click "install" but then it turns back to "get". Same with updating apps. Does anyone know how to fix this?

I would try signing out and back in to the App Store (click Store > Sign Out at the top, then Store > Sign In).
