Haven't fired up the Sim in a while and last night i decided to download the new HTH. Everything was working fine for the first 15 minutes, then my Garmin R10 did an update to the latest firmware in the middle of a practice session. The light started flashing purple really fast. I never seen that before and figured out that it means its doing an update. Everything seemed to work fine for a few more shots. Then all of a sudden HTH would not track a single shot. Tried PW - 5 iron, full shots, half shots, didn't make a difference. The R10 light is flashing green, then red on the backswing, like normal, but nothing gets recorded to HTH. I tried shutting everything down and restarting. I calibrate the R10 every time. Took about 50 shots after all this and it only recorded 1 shot after I moved the ball about 5 feet from the R10 and it showed its flight straight right at like a 90degree angle over the trees. Very frustrating. I'm going to try it again on E6 tonight and see if it is a HTH problem or R10 problem.
