ok, my garmin has quit downloading to my computer. on sunday, it downloaded my time from my quick run around the block with my dog, but then i went out for a long run, and it never downloaded that one. it SAID it was transferring data, but never did (i've just done start/stop/reset/transfer data a couple of times since then too and it keeps saying it's transferring, but doesn't ever show up on the dashboard on garmin connect). it is still in the history log on the watch itself, but will not show up on my computer. i have a 405. any ideas?
