woops, ka72 shouldn't need you to be a member of a team.
The site is linked to the GTC, but I'm fairly sure it will give you an output if you aren't a team member. Perhaps you tried to do a GTC link without realising it?
If you want to join a team, your device may be a problem, I'm not sure if it falls into the approved category.
From the challenge site,
The following GPS's are considered valid for the purposes of the challenge (most preferable at the top, least preferable at the bottom):
* NAVI GT-35 (uses 0.2 sec recording intervals which is approved for this Challenge)
* NAVI GT-31 (uses 1 sec recording intervals)
* NAVI GT-11 (uses 1 sec recording intervals)
* Garmin Foretrex Series
* Garmin Gecko Series
* Garmin Edge (1 second setting)
* Garmin Legend Cx (1 second setting),
Other GPS units can be approved by the technical advisers of the challenge. All software should be set to "Doppler if available" for all categories.
