A new install of AVG and excluding the IL-2 1946 Map and the DGen.exe file separately in Resident Shield - manage exceptions will do the trick. A complete disabling of the anti virus program proved the game went perfectly.
I you install the new AVG version remove the old version completely.
So, problems solved I think!
Thanks to everyone who made sugestions and helped me to find the right way.
