iTunes 9.2 app update bug: The information on this page is outdated

There are a lot of suggested fixes on this page, but only one of them is good ...

Apple - Support - Discussions - Application update all Information ...

Does anyone know of a solution for the 'The information on this page is outdated. Click OK to refresh the page. If you have available updates after refreshing, click Download All Free Updates' message?

I open iTunes the go to the app store and click Download All Free Updates. It always gives me the message that the page is outdated, I have to click OK then it refreshes the page with the exact same app updates and I have to click Download All Free Updates again for it to continue.

This happens every time I have new app updates whether I launch iTunes or every time the iMac goes to sleep and I open iTunes when it was already running.

"Rangeshooter" had the simplest, safest tip. It worked for me. Quit iTunes, restart, try again to install. He suggests its related to iTunes running when a machine goes to sleep.

Other tips involved reinstalling iTunes, deleting apps, etc. They were much more invasive.

I've seen this error message in the past related to an old app, and deleting and reinstalling that app did the trick. This time it looks like a different problem.

Now we see how long it takes Apple to fix this. I've seen some of their bugs last for years.

Update 7/14/10: From Josh Bancroft via Comments, another fix:

After you get the "this page is outdated" error, click on your email address in the upper right corner, to access your iTunes account. It will prompt you for your password. Once you're on your account page, click Done, and you should be back at the "My App Updates" page. Now, updating all of your apps should work.

Thanks! This makes the bug sound like a DRM issue.

Update 7/25/10: Fixed in an iTunes update.
