Pan Not Working After Latest Update

I did the latest update to Studio One, and set up a session as I usually do from a template. However, the individual chael pans do not work now. I checked my I/O but couldn't tell. I made a couple changes from articles online, and I fear I am in worse shape than before. Please contact me with a technician so I can once and for all be sure my I/O are set properly or anything else that would prevent pan from working.
