DM3 driver issue

Last night I installed the DM 3 program on my pc and when I tried to get readings from the system, it said I had to download a driver? It kept saying driver not found? This is my first time hooking the dex to the pc

What is it talking about? its driving me nuts!

I also had this issue when I first installed that program. If I remember correctly, you need to go to the Dexcom website and download the driver from there. It might be an extension file.
