Hi,
I own a 310XT and moved to Express about a month ago. Was able to pair my watch and send data several times, last one being one week ago.
But today I cannot transfer my data anymore. The watch keeps bringing the "transfering data" intermittently, for periods of ~10-15", every one to two minutes, but nothing is transfered.
I tried everything. Restart the watch, take tha ANT stick out and back in, restart the computer, in all possible orders. I tried unpairing the watch and re-pairing it. I tried the instructions in this post: https://forums.garmin.com/showthread.php?123184-Garmin-310XT-will-not-transfer-data-during-sync (both instructions: the one with the folders to delete in the computer, and the one with "transfer all on the watch". Nothing seems to work!
Windows 8.1; firmware 4.50; Garmin Express 3.2.27.0
Please help, anyone.
