new mbp iTunes 10 -> no upgrade available

Hi,

Brand new mbp 15 running 10.8.2 migrated from a mbp 17 on SL 10.6.8 using the Setup/Migration Assistant.

This new mac is running iTunes 10.7 (21) so obviously there are updates available. Using the menu iTunes->Check for updates... tells me there are updates and the choice to download it. Clicking download runs the App Store which promptly tells me there are no updates available.

When I first ran iTunes it wouldn't run saying there was a version issue with iTunes.itl

Renaming that file allowed me to run iTunes but now as I said, it won't update.

Anyone have an idea? Not impressed that my brand spanking new machine has issues already.

thanks
