Ok guys, i'm lost. I have same problem -- Oops! Google Chrome could not find localhost:50000 -- and nothing helps. I added construct 2 to firewall, i used manual to add ports 50000-50100, installed both x32 and x64 bit system versions. But always get this error.
My laptop get internet wireless from router. 2 more laptops using this router (brother and friend), but i don't think that can be problem with these computers. Don't know what to do anymore. :(
