TOPIC: Facebook/ Twitter account already in use

I had a fanslave account few months ago but then I deleted the account. Now I have created a new account with the same email ID I was using before.

But now when I am trying to link my facebook and twitter account (the same accounts I was using earlier) I am getting an error message "this facebook/ twitter account is already in use".

I have deleted the fanslave application that was installed in my facebook/ twitter account but I am still facing the same problem.
