Great work !

The unlock process as in Step 3A has worked well for me - but I found there is one trap for new players. I needed to install each map via its SETUP.EXE, then open MAPSOURCE. It gives a warning that the new map is unlocked . . .just ignore that and proceed. Go to Utilities/Manage Map Products, and select Unlock Regions. Then click Add and enter the code from Jetmouse in the Add Unlock Region box that appears.
