help with updating an app i dont have.

im having a very weird problem, where the mac app store keeps asking me to update an app called codebox. the problem is, i've never heard of codebox before this nor installed it before! typing codebox in the spotlight reveals nothing.

i tried hitting the update button, and a box pops up saying "you have updates available for other accounts. sign in to heinisf@me.com to update applications for that account."

i went to look up that mobileme account and it turned out it belonged to some web studio in budapest (i live in singapore by the way) that ive never heard of before!

anyone know how i can get rid of that update notification that shouldnt even be there?
