Hi Galoub, This may be a stab in the dark here, but a few of my squad mates were in the same position as you, everything appeared in order but yet they could not save a mission. In desperation we checked the all.ini file and found that there were 2 entries for the Thailand map;

 ffb_Thailand ffb_Thailand/load.ini (the thing at the front is a little square box) and
ffb_Thailand Thailand/load.ini - we deleted the little square box and the 2nd line and all was sweet. Don't know if this will help you but worth a look.

CheersnBeers
