I am trying to upload my first workout with a brand new 405CX and I get a 'Failed' message. When I click on the 'failed' message I get 'Internal server error". No luck so I also tried to manually upload the history file from "C:\Users\username\AppData\Roaming\GARMIN\Devices\devicenum\History\2010-01-31-125615.TCX" getting a similar error message and Please try again.
Any clues on this?
