The error I get when I run this is

nueAudio.exe
ArgumentOutOfRangeException
Specified argument was ot of the valid values.

at System.String.Substring(Int32startIndex, Int32 length)
at nueAudio.Form1.makedefault()
at nueAudio.Form1.initializeDefaults()
at nueAudio.Form1..ctor()
at nueAudio.Program.Main()

Any ideas?
