Got the same thing after the update too. 90% of the way there then kaput
Win 7 64bit, i7 3.4Ghz, 8Gb memory, GTX 550ti using non-steam version of DCS World. The default Su-25 DCS World plane works though so it must be compatability with the A-10C module. I bought A-10C through steam over 12 months ago and used the cd-key to activate it on the non steam version of DCS World as I wanted it to utilize the 64bit OS. Always been fine with every update and ran super smooth until the last update, then, same response
