The "Posts reporting this problem will be ignored..." error message only shows up when you do something that's pretty silly, like trying to install the Widescreen Mod on a game that isn't a full install, or one that isn't fully patched. I suggest you read the error line right before it (that is cut off in your screenshot) and fix what it's telling you is wrong.

Too bad this widescreen mod is so freakish to install.. I guess I'll just finish IWD2 or just play torment on 640x480
