I uninstalled and reinstalled all my Visual C++ Redistributable files and it magically got past the Cessna 172 load screen and let me fly the 172 for 2 hours - very realistic - but more importantly, the sim actually worked for the first time since release. No guarantee it will work the next time I bring it up, but it is amazing. Fingers crossed. Just another thing to try . . .
And IF this continues to operate, the next step: get a 737 model released and tie my Jetmax flightdeck back in - its a very expensive hunk of metal sitting in front of monitors now.
