CIVA INS and F1 Super80 Pro. They worked perfectly during install a few months ago, but now they don't work. My F1 DC9 installed beautifully, so I'm pretty sure it's not an F1-soecific issue. The CIVA INS installed on both FSX and P3Dv2 perfectly as well, and worked, as did the Super80. I'm just trying to figure out what could stop those specific installers from running so I can fix it. Since PMDG aircraft don't work in P3Dv2.2 yet, I'll be getting a lot of use out of the older aircraft, particularly the ones that use the INS.
