He'res a workaround solution for your problem:
-1) Close down steam.
0) Then delete your Ef_beta folder in "c:/program files/steam/steamapps/company of heores relaunch". Then
download the link files and unpack them in "c:/program files/steam/steamapps/company of heores relaunch" :
(ask me for the links on steam or check our group)
After that you can play Eastern Front mod again. If you still experience the game not starting try this:
1) right click on company of heroes (new steam version) in your steam game library
2) click on properties
3) there's a button that says "starting options" - click it
4) put in the field following words : -dev -mod ef_beta
Then Eastern front mod will be launched when you start the new steam version.
Hope it helps. We'll work on a real solution within the next days.
Thanks to Tteok Leaf for uploading the files.
