Broke a screw on bracket for Fresco

[renpar61]

I have a Fresco i as center channel attached to the wall with the supplied bracket. As I was tightening the side screw to fix the hinge angle, the screw broke off. Do you think its fixable?
I looked on ML website and sent a message but had no reply. Is there a Customer Service number I can call?
