can I reset Sonar 8.0

I had everything working, the V-Studio 100 connected and controlling Sonar 8 Producer and my Korg Triton Extreme working well.  All of a sudden I messed with the ACT controls and now every time I press a button on the V Studio, I get a midi sound and I can no longer control Sonar 8 through the V-Studio.  Is there a way I can reset Sonar 8 and ACT to a default setting and then reconfigure the midi, audio, and controllers to function without ACT.  Help menu doesn't seem to offer any advice on resetting ACT controls.

Thanks,
Alan
