JT-65 error message when running Flex 6500 on Win 7 Pro. I had everything running and then added another instance to use JT-65 on my K3. Both ran with two different JT-65 programs loaded, but two logs, also. I tried to get both to run on a single JT-65 software install using --rig-name=K3 on one short cut and the same with =Flex on the other shortcut. Can't get both to run, so deleted K3 instance and now can't get Flex 6500 to work. Initially the CAT connects, but when I try to transmit or change bands, I get the error msg: Invalid Parameter While Setting Current VFO mode. Tried reinstalls of both SSDR Beta 1.10.15 and WSJT 1.7.10. Did deep scan of registry to remove all the tails after uninstall. Rebooted before reinstalls. I can get the K3 to run alone with a reinstall, but not the Flex 6500 either as a standalone or as a separate instance. Any suggestions?
