Can't load workouts to 310XT

I installed Garmin Express (uninstalled ANT Agent, no outstanding files lingering anywhere) and now I can't transfer workouts to my Forerunner 310XT.

I tried going back to ANT Agent but when I sent workouts to my 310XT I got an error message that my "device does not support workouts". What?? I've been uploading workouts just fine until this new software.

So I uninstalled ANT Agent and went back to Garmin Express. Updated device software. Still nothing. Deleted device from Express, closed everything, restarted computer and device, did the whole setup again. Still nothing.

Syncing is just one way: it downloads activities to Garmin Connect but it won't send any data to the device.

Creating workouts directly on the 310XT is far too cumbersome to be an option. I'll spend more time creating the workout than actually doing it.

Please help!!

Finally, finally, finally got this to work. I can only assume that old Ant Agent files might have been mucking things up, since I was mistaken in my original post: there WERE outstanding files lingering in hidden folders that I didn't know how to access. Cleaned these out, reinstalled Express, reset my 310XT and threw in a support call to Garmin (thanks, Ben!) and we're in business.

Found information regarding how to locate Garmin files on my Mac in this post, also included below with my modifications for all Garmin files, not just ANT-related ones.

I somehow ended up with 2 versions of the 310XT in Garmin Connect. I only noticed this after I had put the call through to Support. Following Ben's instructions, I first looked up the Unit ID on the 310XT: Mode - Settings - About Forerunner - Unit ID. Then I clicked on Devices and clicked on each device in turn to see if the Device ID matched the Unit ID. I removed the device that didn't match by clicking the cog in the top right-hand corner and selecting Remove. I then sent a test workout to the remaining device...AND. IT. WORKED!!!

A) Reset the Forerunner and clear all user data
1. Power off the Forerunner.
2. Press and hold the Mode button.
3. Turn on the device.
4. Release on Mode button when "Do you really want to erase all user data?" appears.
5. Select Yes.
6. Leave the unit outside, with a clear view of the sky for a minimum of 20 minutes to acquire satellite data before use.
7. I went through the "initial setup" on the Garmin at this point because it started the process - not sure if I could skip it. Make sure Data Transfer=Yes and Pairing=On (Mode - Settings - Data Transfer).

B) Clear out anything Garmin-related from the computer:
1. Access the Macintosh HD/Users/(User Name)/Library folder, which is hidden on a Mac, as follows:
a. Select the (User Name) folder
b. Click Go from the menu bar
c. Select Go to Folder
d. Type Library
e. Click the Go button
2. Go to Macintosh HD/Users/(User Name)/Library/Preferences and move anything that starts with com.garmin to the Trash
3. Go to Macintosh HD/Users/(User Name)/Library/Caches and move anything that starts with com.garmin to the Trash
4. Go to Macintosh HD/Users/(User Name)/Library/Application Support and move the entire Garmin folder to the Trash
5. Unplug the Ant stick.
6. Empty Trash.
7. Restart the computer (I know, it's a Mac, but at this point I wasn't going to leave anything to chance).
8. Plug the Ant stick back in.

C) Go back to Garmin Connect and delete/remove the Device still associated with the account [which I SHOULD have done the first time].

D) Reinstall Garmin Express, go through the pairing, connecting with GC account, etc.

E) Send a workout to your device. Do a little dance of joy when it works. Go back to your 310XT, set up the screens just the way you like them (again) and look forward to tomorrow's run. Finally.

Wow, thanks for posting this. This finally got things working for me again after upgrading to Garmin Express. (XT310)
