I ran into this problem just today actually. It seems like this reddit link proposed using the GM-30 software and shared a helpful download link for it. After several virus scans it came back clean. Once installed, I plugged in my radio, rebooted the software a dozen times to fix the resolution issues, and turned my radio off and on again while plugged in still. This "fixed" whatever issue I was having and I managed to successfully program a few repeaters in my local area. A quick check let me ping the only one I'm in range of and it came in clear as a bell.
Average windows user experience really.
Hope this helps out anyone else like me just now having this issue.
