I just got a new GPSmap 76 CSx, I installed the plug-in at the Garmin website, it shows it was succesful and I can download caches from the Garmin website. When I try to download the caches directly to my gps'r at Geocaching.com I get the message "plug-in was not unlocked successfully" I have restarted my computer after download and still no help. Any suggestions? I would love to download some caches and start hunting!!
