I can run the latest dev build no problems. 1.69.140658

I reinstalled Arma 3 and I deleted my yourprofilename.vars.Arma3Profile with still the same error. I went ahead and moved my entire Arma 3 and Arma3 -OtherProfiles folder out of the documents directory to have them be recreated when I launched the game. didnt work. I put everything back to how it was before I started this process.

Thank you for the update! I will try this tonight and reply back with results!

@Catsy Have you tried reinstalling the game yet? I might try that today while I do other things.
