Upgraded to the new versions of SmartSDR for both the PC (Win 7) and the iPad today. NO problems. I had 3 old versions of SSDR on the PC so I followed the instructions and un-installed them all. Then ran the new S/W and it all went well, took about 30 minutes to do both. Of course, the upgrade on the iPad was super easy, just run the update. Only thing that was a pain was the need to unplug the Flex control knob during the process. It's a pain on my PC because I have to crawl under the desk to get to the cable. Good job FLEX!
