my situation slightly different as staying at home with wife. went to Mukdahan office with wife, girls sat with me showing how to register wife as TM30 host on their PC. Their system gave her username and password based on my email but only did 90% as could not attach files to their PC.
When home logged into the account, loaded a scan of her house book and ID and she fully registered - logged in again, entered my details and I am registered for TM30. Each time I come now no more TM30 hassle, log onto wife's account and report myself for TM30.
