Did you install everything in the correct order (ie campaign, map pack, vehicle pack and finally, infantry pack)?
Did you click on the button "Extract all maps"?
Did you make sure that the paths is the correct ones (cause it seems to me that the game cant find some of the files (2nd screenshot)). The DCG_environment file is created by DCG and thus, that file does NOT exist until you´ve succesfully started a game in DCG, so don´t waste any time looking for it).
If you follow the 17-step-by-step guide I wrote above your posting, everything should work as it is supposed to do. But please check your paths, it is crucial that they are correctly entered.
My own paths look like this for example:
Men of War C:\Program files\505games\1C\Men of War\
DCG Mod Folder C:\Program files\505games\1C\Men of War\mods\Campaign
Save Folder C:\Users\Zeke Wolff\Documents\my games\men of war\profiles\zeke wolff\save\result
~Zeke.
Ps.
Don´t worry about your English, it was perfectly understandable what you meant and I´m not a native English speaking dude either...
