Well, there's not really much more to tell. I tried to do everything Coreymas suggested and yes I checked did I install the patch in the correct folder. The game without patch itself works fine, but when I install it and launch the game on the top of the menu I can see Doomsday Armageddon v 1.2 (VBLV), so everything seems fine, but then, after I launch a scenario the screen goes black, the music goes on and after few seconds I get the ordinary Don't send error. Yesterday I got my Windows XP reinstalled but the problem didn't solve. I tried the pach from the different sources, I tried to install the game into different places and it all didn't work. Just doesn't know what to do next.
