Ufasoft x64 windows miner doesn't support stratum?

Hello there. I wanted to build the ufasoft compiler myself, but I'm lacking a whole lot of dependencies, so for now I just wanted to test if I could simply run it on my system. I've run the 32 bit (coin-miner.exe) - however only CPU was available (I have x64 gpu drivers) - it connected to the pool, and worked fine. I've turned on bitcoin-miner-64.exe, passed exactly same parameters as to 32 bits. Both CPU and GPU were detected, but... "Error 80072F78: The server returned an invalid or unrecognized response". Wut wat, what have I done wrong? Thanks.

Also - did anyone else tried to build this miner under windows? The project has many filepaths outdated, weird order of loading (mc.exe is called too late and we get resource missing problem), and other stuff.
