Unique tech areas??

[Abyssian]

I am real new to this game and am just starting to sort of learn how to play. I am not real familiar with the whole MOD thing but I did download "the Ultimate Mod" from Spaceempires.org. Among certain technology trees that seem to be lacking - and I understand from some other Posts I have read that this MOD is incomplete and may be patched to add-in the "missing" techs - I have noticed when I land on a planet where I have "detected advanced" technology, I never get anything.

Having looked through some of the data .txt files, and not understanding a lot of it, I see there are 12 unique tech areas available in the ultimate mod. But I never get them when I colonize a planet. Am I missing something??

Sorry if it's a newb question. I haven't been playing the game very long.
