Thats one thing to check, although I think that is unlikely because I vaguely remember that you had to do something weird in order to change the channel. Hope that helps. I will try do some testing Monday.
MSB for the team number on the OI has to be changed to "1 / ON" indicating a high team number (off the top of my head, I don't know what it is, but I believe it is in the 3000's) Then you have to change the channel DIP switches on the OI into a specific sequence for the various channels. THEN you have to tether the RC to the OI and let it resync the team number. Finally, after all that you will be running on the secondary channels.

As for the red vs blue, I have a feeling that IFI changed the master code to reflect the new indicator. Keep in mind, at competition you have a 50% chance of getting on a blue channel.

As for getting your light to work, check that the relay is working correctly, and check your PWM cable (they DO fail). If you have a steady hand, you could use a voltmeter on the Team color pins and confirm that your RC is putting power to those ports.

If you know any teams around you, try contacting them and seeing if they have spare LED block from a previous year that you could borrow and confirm your RC is ok.

Having someone else double check your wiring and cable termination is also a good suggestion; not everything goes as planned when you're working late at night and mistakes do happen.
