1. Consider upgrading ASAP
2. Do you have Power User rights? Try logging into GP (or have someone log in for you) with the SA user id and password and see if the problem still exists.

I would check the Account Level Security and make sure it is not activated, please go to Tools>> Setup>> Company >> Company and make sure that Account Security is unchecked, if it was checked and you have your account level security was correctly setup, you need to make sure that the user you are using own access to all accounts.
