Reply to VCI-100 sensitivity knob fell off!!!

So I was playing with the sensitivity know and when I was turning it, it fell off. It just f-ing fell off. I recovered both pieces from dis-assembling the unit and was shocked when the right job wheel gave me the red light of death. After further fiddling (god must have been on my side), the job wheel was acting normal. Everything is ok now, with the only problem being that my sensitivity knob is sitting on my desk. Any thoughts? Thanks guys
