Korey,
Your reply is not welcome and is a true show of HOW NOT TO HELP.
If you bothered reading the other threads (which you haven't) then you would
realise why I responded and it's a general response, not just to one person.
I suggest you find something better to do or spend the time looking at all
the threads before you "march in".
All the best.

Why do you respond if you have absolutely no idea of how to help? The
gentleman is using AFSK and has a problem with the MMTTY plugin. If you
can't help then don't say anything.
