Hi, if you just installed RoE you might come up with the wrong CD key error. The easiest legal way to fix that:

1. Close the game, go to your Steam library.

2. Find in the list original game – Doom 3

3. Right click on the game title

4. View CD keys

5. This is the required key, write it down

6. Launch RoE, paste in the >> first row << the key. RoE key should be inserted already in the second row.

That’s it, no additional installation needed. Enjoy your DooM!
