Aperture will not open "because of a problem"

[Mjmar]

I got a MBA a few days ago and recently finished putting all of my apps on it. When I tried to open Aperture 3 it said that it can't open because of a problem. I purchased it from the app store, and tried re-installing it but i got the same error. Has anybody had or heard of this? I'm not sure what to do... Thanks.

Did you remove Aperture from /Applications before trying to reinstall? If so, try maybe installing from another user account on the system.
