It can't find a .wad file? Is that what it says? If that's the case, then you need to get the .wad file from somewhere. It should've come with the map when you downloaded it, but if you got it off a server, .wad files aren't automatically downloaded. Contact the author if you can't find the .wad file, or ask someone for it.
Including textures isn't difficult, I don't know why mappers don't do it. -_-
P.S: Why the heck is Ã¨mbed filtered as a swear word? (Sorry for breaking a filter word, but there's no other way to type it!)
It has been left as a swear as a precaution for now due to a recent incident. ~Pain
Yeah he is probably missing the .wad file. Which means that he installed the other stuff. Don't put the .wad file in any folder in the esf folder. Just go to the esf folder and stick it in there, dont click on any folders that are in the esf folder for the .wad's. hope that makes sense.
