...your not the only one who have problems using this sound mod compilation, maybe the reason is simple, the readme file is to long and ppl are to bored reading and understanding it.
The readme is telling you that you have to alter some keyb. assigments in TDW options file if using TDW UI, finding some free keys for some functions.
...plz guys be so kind and read it, the time needed creating this is nothing in comparision for taking the time to read it carefully.
