Cannot connect to iTunes music store

[gduncan]

My wife and I both have accounts in the iTunes music store but we are not able to log into either account. When we try we are presented with an alert box letting us know that iTunes cannot access the Keychain. The exact wording:

-------------------------------------------------------------------------------------

iTunes could not connect to the iTunes Store. The requested Keychain
was invalid.

Open Keychain Access and run Keychain First Aid, then try again.

-------------------------------------------------------------------------------------

I opened Keychain Access and ran the Keychain First Aid as suggested but that did not correct the problem. We are still not able to log into either account.

Anybody have any idea how to fix this?

I was able to fix this by deleting the /Library/Keychains folder. I can't remember if I had to log out afterwards or not but the OS recreated the folder and I was able to buy music again. I noticed that there are some files related to file vault in this folder so I'm not sure if this will effect file vault or not.
