For the past couple days, I have been attempting to update the contacts list on my MD2017. When I try to write to the radio I get an error saying that the software cannot connect to the radio. It's worked fine dozens of times before. I checked and the computer sees both the cable and the radio. Just to make sure, I tried another cable I had laying around. Same result. I have no idea what is going on here. I'm using software version 1.22 and I have the 100,000 contacts upgrade in the radio.
