Windows 10 64 bit has been running SmartSDR in the past. I uninstalled SmartSDR and then installed SmartSDR 1.9.9, radio chooser said to upgrade to I clicked the upgrade button and the yellow progress bar made it slowly to the right and sat there for fifteen minutes all the way to the right. I closed the radio chooser and restarted SmartSDR v1.9.9 but the radio is no longer in the radio chooser. Front panel of radio was looking normal - blue light and my call sign displayed on the front panel. I shut down and restarted the radio and now radio shows up in SSDR chooser but when I connect to the radio, there is no waterfall or pan adapter but the SSDR user interface was responding and I could change frequency. SmartSDR 1.9.7 was working fine before this.
