1. crossfire 1.6 is old damn old.... there were several other versions after that which fixed sux bugs 2. the 2nd mission was playable in 1.6 but it simply was too hard (the right timing was needed to finish this mission) 3. to read the manuals and the official mod pages does often help to find out whats wrong 4. like i said CF 1.6 is pretty old so use a new version - CF 1.7 is the most used and most popular FL mod in MP and SP atmso give it a try
