Updates for iPhoto and iMovie in the Mac App Store

Hi,

I recently bought a new computer running Lion. When I started using the computer, I opened the Mac App Store and signed in with my Apple ID (the same one I've always used for buying apps from there, music from the iTunes store, and apps for my iPhone). I am able to easily access and download my old purchased apps to my new computer without a problem. However, in the updates section it shows updates available for both iPhoto and iMovie, but when I go to update them I get this message, "To update this application, sign in to the account you used to purchase it." iPhoto and iMovie came on the new computer, and the only Apple ID account that I have ever used is the one that I am currently signed in under. Does anyone have any idea how I can get these updates, or at the very minimum, get rid of them so that they do not show up anymore (frankly, I find the red circle very annoying, and I don't really use either of these apps so I'm not too concerned about them).

Thanks!

Sorry, I found a few other questions about this same thing after posting, so I'll try those solutions.
