Thanks for your help. Wow, what a nightmare, but I think I've got it now. I uninstalled dcs world and all dcs programs, then reinstalled bs1 up to 1.0.c or thereabout. Could not get TR 5 to work even though it showed up. went down to 4.whatever for my tr5 and it would work, but it's not all that hot, no smoothing, some other stuff. I was rummaging around the Track IR site and there was a suggestion to dl the newest software and save it to the desktop, not run it from dl manager, and then to run the setup program with administrative rights. Well, it worked. I've never been able to run the latest TIR program, only the second last. So any way, seems like I'm okay on that front. meet me in the Black shark forum 'cause my cockpit is all messed up in missions and instant action. it's like Alice n Wonderland white rabbit 3d stuff hanging in the air. Lol, it never stops. THanks again. wiiired
