please help me.

To work with wads. Drag them into Zdoom.exe (the icon with the marine in it) and select an iwad that fits with the pwad. Ex: If the pwad is for Doom 1, select the Doom 1 iwad once you drag the pwad you want to play.
Here is the site for wads:

Your disc is most likely a shareware version of Doom 1. It is probably a demo disc or something. Did you bought the disc from a store, or did you bought it from somebody?
