I found an old thread below and tried clearing my Temp Internet Files and deleting the site from the Adobe Flash settings as suggested but it didn't work.
https://forums.garmin.com/showthread.php?7340-Garmin-Connect-quot-Player-quot-Map-not-displaying&highlight=player+adobe+flash
Adobe Flash is version 11.3.375.10 which is the latest per http://www.adobe.com/software/flash/about/
Adding connect.garmin.com to Trusted Sites didn't help.
Any suggestions?
