multi fx for hopper wagons

[rjw1975]

I`m running trainz 2006 and read a forum from 3 years ago about Wulf_9`s multi fx for hopper wagons. It said to replace kuid104722:2501020:2 with kuid104722:2501022:2 and that it would work fine, since its got no errors like the previous one does that can`t be fixed.My problem is that after doing this and changing the kuid # in the appropriate hoppers, when I go into driver and go to the coal mine to fill them up I get the following message for each hopper, "mfx: features disabled on (name of railcar) due to missing config data" . Also there are no sound fx. Is there another multi fx asset that works to replace this or am I gonna have to use the old one with the errors just to get sound? Also , I`ve read that using assets that are faulty or have missing dependencies will cause trainz to run slower in driver, if so how much of an effect does this have, since I`ve downloaded a few things that I as of yet can`t seem to fix?
