Just an FYI for those seeking help on this.
There was a guy on F_chat that when by the screen name Dave rocks ( Dave Lelonek )that restores buttons and switches.
I do not know him personally I just remember him because he lives in Orchard Park, NY (Buffalo NY) I grew up there.
Anyways he is now banned from F_chat however I can access some of his threads on this subject .
It seams as he has a good bit on knowledge and experience in restoring buttons so this may be of help for those having problems here.
Below are a couple YouTube videos from him. Again this is not an endorsement of him or his services, so do your own due diligence.
Best of luck, Vic
