Those settings are straight off the GPSTC guide, so I cant work out what to do... To do date I havent got any windsurfing sessions yet, so they arent important. Ive been trying to get it right with bike rides so I dont lose any good data i might get on the water. Any help will be greatly appreciate!
Looks like your files generate a problem on the server when it tries to process them. Try and download a free demo version of Realspeed or GPS Results and see if you can open them and see your results, otherwise your gps might generate corrupted files.
Thanks for that advice, I got GPS results as I have a mac, and this what it spit out;
I have no idea what i'm looking at there, or how i'm supposed to put that onto GPSTC, but it might help someone here solve the problem? I literally just rode out of my driveway, along the road and back, but that should still enough to extract some basic data... From what I can tell with my limited knowledge is that the GPS is working fine...?
I'm not familiar with gpsresults, but that looks like it's saying you have a 2s average of 9.943kts.
You also need to select the 10sec, 1hr, 1nm, and @500 to get the rest of the GTC divisions, then for the 5x10, you take the bottom right figure, {Average (5)}.
Yes it does look like it's working OK, maybe Dylan can solve your KA72 problem.
You can post manually to the GTC with the GPS results numbers.
Ah I see, I just found that. Might save some mucking around! Thanks for that, I'll get out on the water and see how it goes! 
That looks like it is working perfectly well to me.
After opening your file go to FILE>SAVE RESULTS, This will make a text file to save of every division.
At the bottom left of the screen there is a small box with '10' in it. You can change this to '5' so you only have the top 5 results for each division.
At the bottom right of the screen is the 5 x average of each division. If you select 10 sec, it shows the 5 x 10 sec average.
There is also a menu item to directly send the results to GPS-Speedsurfing.com if you have a log in for that site. I will ask if Manfred is able to make it do this for GPS-TeamChallenge as well. 
the other thing you can do also, is "Save As" a .gpx file, which you can then open with Google Earth and get an overlay of your path :)
