I just downloaded SmartSDR 1.3.8 and it won't install. The radio shows up with the yellow dot under it. But, wihen I click on the radio and the the yellow Update button, nothing happens. The Windows Task Manager says the three programs (Radio Setup, SmartSDR Alert Helper, and SmartSDR Cat Ver 18.104.22.168) are "Not Responding." I've never had a problem with upgrading before, so it sounds like a bug. I'm running a Win 7 64 bit machine with a Core I7 Extreme processor and lots of RAM, so it's not the computer.
