Changing the ingame sounds on ECE 3

[ntanswell]

Hi,

I have sucessfully changed the in-game sounds from the standard EB ones to the ones featured in Pro-Train 4 Hamburg to Berlin on ECE Part 1, Part 2 and Parts 1 and 2 combined just by copying over the ingame.sms and associated files from PT4s sound directory. I have tried to do this with ECE3, however the old EB sounds still play. How do I apply the PT4 ingame sounds to ECE 3 with parts 1 and 2 joined?

Thanks

Nathan
