retail version of coh

I have a purchased legit version of coh (deluxe edition) which include all three of these: coh the original, opposing fronts, and tales of valor.
Is there anyway that Eastern front will work with this?
Blitzkrieg Mod runs fine.
Current Coh is up to date.
Thanks

You need to register your keys on steam, download and use the new version with EF. If you play with any other version it is not going to work.
