Just to clarify, I believe the general recommendation is:

"Try deleting the files "intrface.bbw" and "mysetup.dk" from the Band-in-a-Box folder (usually C:\BB). This will return the program to factory settings."

That has the bad spelling and includes one other start up file.

But generally Matt has it right so maybe this is old??
