Plug in the GPS receiver first, then start SA2008.
In the Options window -> GPS Settings tab, make sure Device is set to DeLorme Earthmate and Port is USB.
After doing the above steps, try clicking Start GPS. If it still doesn't work, check that USB port with a flash drive or any USB device to make sure it is working. You can also try the Earthmate in a different USB port on your computer. If these steps don't work then your GPS receiver might be bad, in which case contact DeLorme.
