the account is obviously taken just try to make up a new nickname that no 1 will think of, then when it doesnt work try it only once and use another name, u cant do anything about the error as it is a security measure and u must wait about a min of 3 hrs until u can try another password also, sum1 else did this are u sure u r actually editing the nickname line when u put in a new nickname and not the profile line, check tech support thers a similar problem and a better explanation there
