Global Payment System Error

I have this error message:

PCI::Error during transaction

The Global Payment Transaction System Identification numbers are incorrect. Call Merchant Service Provider.

I use Authorize.net

I have YES = Authorization Only

I have re-newed the transaction key.

Please advise since I cannot process any credit card payments.

Please remove the empty space that is added before the API Login ID, re-connect the form with your Autorize.net account and test it again.
