I upgraded to fw SSDR 2.6 all regular the first time. I closed ssrd and pc and left, when I restarted the PC and launched again ssrd the sw asked me to do update bringing the radio back to the old version 2.5.1. there is not any way to lunch the software. How to solve?
You have started version 2.5.1 of SmartSDR. The Icon you want is at the far left side of your screen, labeled SmartSDR v2.6.0. You can have both versions of SmartSDR on your system and if you start the older one, it will ask you to downgrade your radio.
I would recommend deleting the SmartSDR v2.5.1 shortcuts from your screen.
