Missing Single Missions

[mjfur]

I had stock 4.11.1 installed and working correctly. I installed HSFX 6.017 and all seemed to go well. The only issue that I'm having is that none of my Single Missions display whether I'm using stock 4.11.1 or 6.017. (The Mission Folder is installed in the IL-2 1946 Game Folder and contains all of the missions.)

When I click on Single Missions, the menu opens and the Airforce and Mission Type fields are populated and function, Mission Files are blank.
I've tried adding _RU after the mission name suggested by 242 Squadron;

Problem (General) -All mission briefings are either missing or in
Russian.
Detail : This is because all mod versions use the Russian version of the game.

Solution - Copy the mission briefing file:- eg. MyBrilliantmission.properties
Then add _RU to the end. So it becomes MyBrilliantmission_RU.properties

Still no luck. Any ideas?
