I have no idea what you're saying but I'll try to help.
You have downloaded Doomsday which is an engine only - and it works very well. You still need to have the WAD files from the original games (Doom, Heretic, HeXen) in order to play them.
The engine is trying to tell you that you need to select the folder where you have your original games.
If you don't have the original games then you should still be able to download the free shareware versions of Doom and Heretic from various places on the web.
If this isn't your problem then please try to provide a little more detail instead of ranting, you're less likely to get help doing that.
