I am for the last 45 mins trying to register for NASBA SINGLE SIGN ON and this is the error it gives me-“Invalid combination of user information. Gateway User not found.”
I have tried combination of all the things people have suggested online and i am not sure what is wrong. Can someone help?
I thought after I got my NTS notification, all i had to do was register for my CPA exam at Prometric.
