Push !

Hello there I want to download this version, can you help me?

My workshop projects are invisible and so is my awacs.
Please let me know what is wrong.

Sorry to bug with dumb question, but i am a little bit confused. I have a GOG version of Xenonauts , updated, and i clearly followed instructions in forum thread to install the X-division mod. All was smooth and dandy despite some minor GUI issuses witch did not bother nor affected gameplay. I played a bit, suffered a lot but sucseded as well in game. Untill Phase4. Apparantly, i can't find Alien big computers wich i need for all of aircrafts after Sonda. And now i can't deal with Air superiority wings and generally eat ♥♥♥♥ with 5 continents lost and me making last stand at north africa, occasionally putting down soft or slow UFO's.
So, the question is, which tech's are needed or wich UFO's i need to destroy to obtain this freakin big computers? Tired of being able to take on alien fortress but ultimatly loosing in air and in general to the base-spaming alien goofballs.

Also i never met a single alien mech(
wtf

Sorry for my english, i am not a native speaker. Will be extremely thankfull for the answer\advise\smth.
