Ok... let it go peoples, we all act dumn sometimes. And by the way oneway9341, you can push the key under escape, the type addfile shadow.wad, for example and it will come up saying its loaded some lumps or somethin, and if you want to load a level, say for example scr_mysticrealm.wad, you type addfile scr_mysticrealm.wad ( make sure you put a space between "ADDFILE scr_mysticrealm.wad not ADDFILEscr__mysticrealm.wad.)
There you are.
EDIT 1 - By the way, if you want to use the launcher, but its a lot of trouble seeing as half the time it has some error.
