ZDoom won't work. Please help.

Uh, I can't run ZDoom.

It draws a black window, deletes it then returns an error:
GETLASTERROR=2

What do I do?

do you have the launcher? get it and go to file\preferences and set the path to zdoom.exe this should od it. its ussually my problem when it doesnt work

uhm.. you probably should ask this at the forums at http://zdoom.notgod.com as randy (the author of zdoom) probably knows whats wrong.

afaik i've never seen randy here :)
