Intitially had the problem when trying to download caches to my brand new Oregon 400t of getting the error mesage 'The plug-in was not unlocked successfully' and thought I had resolved it by upgrading to Premium Membership (see my post yesterday). However, it's back.
So what have I done since then:
1. I've used Windows Explorer to transfer a Wherigo file to the Oregon
2. I've installed a mini-SD card of street maps
With the card installed and the Oregon connected to the USB, I get the Windows Autoplay options on the PC and the Oregon goes to the Menu screen, not the connected to PC logo screen. I can't do anything from this screen and when I try to transfer cache files I get the 'The plug-in was not unlocked successfully' message.
If I take the card out, I do get the logo screen but when I try to transfer I still get the error message.
The Garmin Communicator Plugin page on the website shows me the unit is connected properly.
Any ideas, anyone?
