I dunno if this helps, but the theatres showing no missions are the ones used in EEAH. Which also do NOTHING, NOTHING AT ALL in my copy of EEAH. In the store page description it says EECH should "link" with EEAH. So maybe manually copying the mission data for "Cuba", "Georgia" and "Thailand" will work? Not tried it yet though. Going of the store page this should be automatic, or maybe you need to install the two in the same directory?
TBQH I wouldn't bother, what I have seen working in EECH so far, and from previous experience with EE2, it is not worth even a minute of your time.
PS/ It worked! The three relevant directories within both EEAH and EECH are "maps1", "maps2" and "maps3", just replace those in EECH with those in EEAH and the campaigns / missions should now work in EECH. Good job as EEAH just does NOT even work at all........ just don't expect fun though. EECH campaigns are just seething, buzzing chaos. No ryhme nor reason. Quite frankly, I hate the game.
I was a fool to buy them, half hoping they'd be better than EE2! I bought that way back in the naughties on DVD! EE2 stank! Ergo these earlier incarnations should also stink. But logic ain't my strongpoint and I bought anyway! :)
