First and most important thing - Thank You for help Shakaali.
I changed paintschemes files for one from backup (mine was 6GB big, that one is 2GB only)
I deleted all DCG files. reinstalled and configured as needed. DCG knows where is il2.exe, missions > campaign > Coutry folder (UN for example) > Midway> allcamapign.dcg searched by the searcher, not find by myself in direct folder.
<<no campaigns active>>
Now, start the game. And I can see these campaigns, I'm choosing one and click to create. For first three times it worked. Now, for the fourth time it CTD again with windows error sound and popup Il2DoF/TIR Enabled Executable for modded IL2 Sturmovik 1946 does not response.
+ I turned on these campaigns. Everything was ok till I wanted to end, CTD and that crash has deleted my pilot profile completely. It was pilot profile specialy made to create DCG campaigns for safety.
Update: I think I must write about one more thing, while I'm trying to configure one more time, the DCG, I cannot find any allcampaign.dcg files by hand. Only by ,,File'' icon in dcg browser. I can see there old campaigns which now doesn't exist.... But I cannot find any old installation of dcg.
