Problem with Nanocomposite armor production

[darckense]

Hi all,

I'm currently running UFO:AI version 2.4 dev, with a linux 64-bit build (source downloaded on Sep 7).

I researched the nanocomposite armor, but when I want to start production, I get a pop-up warning:

Not enough materials -
You don't have the materials needed for producing this item.

Does anyone know what I'm missing ?

Thanks,

you have to collect more alien materials - disassemble crashed ufos

OK, so I have to do more research first. 

Thanks for the tip. I didnt understood from the research report that I needed alien materials for the nanocomposite armor.
