If you are having trouble syncing workouts:

• Make sure that you've entered the username and password for your Concept2 Online Logbook in the app Preferences. You must enter them exactly as you normally would to access your online logbook at concept2.com. They are case sensitive.
• Make sure that you have a good internet connection.
• Make sure you have new workouts to upload. If ErgData finds the same workout in your online logbook, it will not re-upload them.
• Make sure that the dates on your new workouts are not in the future. This happens when the date on the PM is incorrectly set to a future date.

If the problem persists, contact Concept2.
