I went down the list doing things step by step as suggested and was doing fine until I actually attempted to log onto the view bill site and got this:
Invalid username and/or password. If you ordered your service through a reseller of WildBlue, please contact the service provider shown on your billing statement.
That's what I've been getting all along, so I'm still SOL.
Guess I'll have to call them up and hope for the best. I'm spending way more time trying to get this all running properly than should be required, so I think I'll have to start sending them a bill for time invested.
