Any one dealt before with T1 efile error code # 99173? the warning message I am getting is “the TransmitterEfileNumber” element in invalid according to its data type “token” - the Pattern constraint failed.

My efile number and password are valid and renewed and I efiled T2 week ago, now that I want to file T1 I am getting this warning message

appreciate your thoughts on the solution. thanks in advance
