I have a forerunner 310xt which will not occasionally download its activities. I am trying to get the activity stored on thr watch to my garmin connect account via a Windows 7 64bit PC. The activities in question get stuck whilst 'uploading'. I must stress that this is only occasional. This will remain this way as long as I leave the window open.
I have tried to attach a screen shot of the window showing the activies transferring, although this fails whilst uploading to the forum. Anyone else struggled whilst uploading bmp files?
