Did you play on 1.09 or 2.02 before? If yes, make sure they are completely disabled, including any music.
Start the Edain Launcher and see if it finds any updates.
You can also go to your VirtualStore (\AppData\Local\VirtualStore) and check if there are any files in the RotWK folder in there. If yes, delete them.
If the mod still doesn't start, a clean reinstallation fixes most issues.
