No updates currently available....BUT there are

Background info: Got my MBP a week ago. Switched iTunes over to it instead of my old pc. No problems switching. Everything seemed to work fine..... I have an iPhone also.

Now, the app store shows there are updates available. I know for a fact there are updates available for my iPhone apps. When I click on the app updates in my library it then says: "Kevin ( ****@yahoo.com) has no updates currently available. To check for updates for another account, sign into that account."

I haven't tried to purchase anything from the store since the transfer to the MBP..

Any Ideas??

Thanks
Kevin
