keychain access limited

I have two computers (one for me and one for my wife) and have kept them synchronized using mobile me. One of them had a problem with the keychain so I synchronized it and had it replace everything on the computer from mobile me. However now all of the keychain items come up with a message that says access restricted on this computer?? How do I correct this problem? Is this the correct discussion group for this question? Thank you in advance for your assistance. MACarmel
