Forerunner 405CX - Garmin connect can't see one activity

I have a Forerunner 405CX. It has uploaded activities fine but failed to upload my run on Tuesday for some reason. I have tried un-installing and re-installing Garmin Connnect software and drivers. My computer says that it is reading my Forerunner and appears to read other activities fine but not my activity on Tuesday. I went for a run again this evening and this activity uploaded fine. I can still see my Tuesday run as an activity on my Forerunner but for some reason it will not upload to my computer and Garmin Connect. Has anyone encountered a similar problem or can they suggest a solution?

    Twice I've had this exact problem with my 310. Never have found any solution. Will be interested if one is found.

    Can you send your activity to Training Center?
  • Same here... I can load it to Garmin training center but not to Garmin connect

    I've recently had the same problem. A run I did after a bike on with my 310xt isn't uploaded by GC or the desktop training center, but it shows up on the watch itself just fine. I did the bike, reset the unit (held lap button until reset), then switched to run and started. The bike imported fine, but can't get the run in through the auto upload or manual.

    Exactly the same problem, with a run did yesterday, October 4th. It uploads the run I did on 3rd October and the one I did today (5th) October... but strange thing, why doesn't it upload the other one? any hints?

    Thanks

    This file contained trackpoints with dates in the future (November 29, 2009). After removing those bad trackpoints, I was able to upload the file (I'm attaching the file). I don't know how the bad trackpoints got in there.

    I had the same problem. When i tried another computer to upload the track it worked fine.
