I was syncing my 910xt in Garmin Express and my watch battery died. The file never uploaded to Garmin connect. I have tried recording a new activity and then re syncing. It syncs the new activity but not the old one that failed uploading when my battery died. I have tried "transfer all" and it just gives me an error message saying, "The was an error syncing with Garmin Connect". I am running windows so I can't use Chuck's method to manually extract the file. Any suggestions?
