I used my trainerroad setup for the first time this AM. My setup is my Rockhopper Mountain Bike on a Satori TACX turbo trainer set to resistance level 7, a Garmin GSC10, Garmin HRM, and a Moviestick USB ANT+ receiver stuck in to my Macbook Air. Everything works perfectly right away. Apart from me 
I did the 20 minute test and it told me to lower my FTP to 165 Grrr. Really need to get stronger but I am focussing primarily on running right now.
What plans are you using on there? How are you finding it? I was thinking of starting with 2 sessions from the Intermediate Build Phase I mid week and then a club ride on weekends if I can manage it or the third session from the plan if I can't.
Here is my weak 20 min test: http://www.trainerroad.com/cycling/rides/86157
