Show Buddy & DMXIS Forums

I've been using Show Buddy and Show Buddy Active now for a few years and love it but all of a sudden i'm getting random audio crackle on tracks I've been using for years, Sometimes when I open SBA and play a track it produces no music, just random buzzing noises!!!

Im using a new Macbook Air and I've changed cables, checked the mixer and checked the tracks through other software and everything it fine.

Any Ideas????
