I purchased a padKontrol this week, and after a bit of experimenting aand reading up, I'm starting to get somewhere (I'm a midi virgin

Problem is, I installed Superior Drummer Korg Edition, which was bundled with the padKontrol and nearly all of the files look like they are corrupt.
When I launch it as a VST, none of the drums do anything apart from one kick drum, doesn't matter if I use my padKontrol or just click using my mouse. I looked in the folder where all the sounds are kept and the wav files won't open up. I also get a message on launch saying the files may be missing or flawed. Anyone know a workaround? I've tried re-installing 4 times.
I basically want to try it out, although my main use for the controller is to trigger samples and control effects, I really want to try out supreme drummer as I may want to go that route if I like it.
Thanks
