I was having this problem. I seem to have been able to solve it by switching my language from English to British English in the System Preferences. This is what my language settings should have been anyway and I'm not entirely sure why they were not set like this.

This did it! I switched to British English, logged out and back in again. iTunes launched and then I switched it back to American English and logged out and back in again and it is all good!

Do you know if you did the full install from the www.apple.com/itunes/download webpage or from software update?

Doing the language switch didn't work for me. But I went to Apple's website, re-downloaded iTunes and reinstalled it. The reinstall fixed the problem. I guess the problem was with the iTunes version installed from Software Update.

Same problem here...did the download (10.6.1) from software update. Switching to British English does launch iTunes...but I'm in America. When I change back to English in SysPref, I get the has not been correctly localizedmessage again. Any other suggestions greatly appreciated. BTW, can't just reinstall from the Apple site, because it's still offering 10.6. And that was a problem too...caused my iMac to crash iTunes in grid view.
