Bill,
Did you fill out a support ticket? (I feel you did) Did you get an email from MTU? Have you looked at the ticket since you filled it out?
In other words, if you have an open ticket with support they should be talking to you through the support board. If not...
If none of this is going on, you need to start a new support ticket.
MTU has to make this change on their end, there is nothing we can do, we're just Karaoke guys like you working at home. MTU wants you up and running, we'll get you there.
Jim
