Change my Origin Account on PS3

I have two accounts on PS3, and I registered the game Need For Speed Most Wanted in an Autolog account, but then I went into the Origin site, I changed my registration to another account, but still can not access the new account in Autolog .
Always the same message appears: You have previously connected to Autolog with a different account.
Please sing in to That account to connect.
In That account was used in error please contact Customer Services.
What should I do to change my account?
