I've had a nightmare install, too. First, I had an install window of 10-5, and then I get a call at 4:45 that they reassigned the job to another tech, and she won't get here for half an hour. Then, once the first Hopper was installed, it wouldn't receive the channels on transponder 129(? whichever one has TMC and Comedy Central). Then they, (someone else has come to the party at this point) tried to set up a Joey with the second Hopper, which is working fine, and it won't go past the software download after 80 or so minutes of trying. They're coming back tomorrow at 9:30. I'm so disappointed.
(Also, for whatever reason, the first Hopper won't keep one channel in a favorites list I'm trying to set up. It just doesn't like that channel.)
