I downloaded this complete (2.5 GB) but whenever I start the GPS I get a message saying (can't unlock maps) I tried to unlock using jetmouse and Garmin_kgen_1.5+Fix to generate a working gmapsupp.unl to no avail. There is no way for me to find the card ID and I have a 32 bit operating system. my GPS is Oregon 450. Please help me if you can. Thanks in advance folks.
