Open the Grex loader, do not try to find yet. Cycle power to the G100, as soon as you power it back up, start clicking on the find Grex radio button in about 2-3 second increments. It will time out in about 10 seconds. If it you don't find it within 10 seconds, 2-3 clicks, start this over. If you don't find it in 3 times as described, let me know.
