Dmz is off (also ran the setup again, first, lost connection with all computers

) then ran it again, didn't change anything for the computer with the rror
also, as sad, i cannot get a new router during the hollidays (and after the hollidays, i'm kinda busy with school, getting a test week soon) i will get one after that week, but i need the computer for now (and ill check if it is windows 7 compatible)
