I had the same issue.
Go into Applications/Manage Apps/All/Market and on the top right mine said something like 'Uninstall Update', tap to uninstall. The app doesn't actually uninstall, just the 'update'.
Since then the market has loaded all my apps. Hopefully this fix 'sticks' but I've rebooted a few times since and all is still well.
