iPhoto and iMovie not reinstalling

[BhaveshUK]

Hello,

Yesterday I let my little brother try out my new mac for ten minutes and he somehow removed iMovie and iPhoto. Whenever I try to reinstall them from the mac app store I get a message telling me:

These apps cannot be accepted on this computer
future updates of these apps can be found through software updates


Im at a loss on how to get these two apps back and any help would be appreciated

Make sure you are using the same AppleID in the App Store as you did when you signed up for an AppleID when you first started Lion and registered. It is tied to your Lion install AppleID.
