zdoomdos says "cannot "-file" with unregistered version and i "-filed" the

Wow! Did someone prune this forum or what? I need some help getting zdoomdos to work on my dos computer. I copied the ZDOOM files from my windows computer plus the zdoomdos addon thingy and put them in one directory on my dos computer. Help, is something missing?

Are you using the shareware iwad (doom1.wad)? You cannot use mods with the shareware version of doom.

I am using doom 2
Do i need to copy the iwad into the directory of ZDOOM like boom?

It would be best if you copied the IWAD, yes.
