K9DUR Voice Keyer Setup that will definitely WORK!

I have tried to install K9DUR Voice Keyer. I have the receive audio set to DAX 1 and the transmit to DAX TX. But I am trying to use Port 8 which I have set up in CAT to key the transmitter. The issue I am having is this, the transmitter is keyed. The message that I have in Key One is not getting transmitted over the air. Even though I have K9DUR to go to that specific directory on my hard drive. I have Com 8 setup in my CAT. I have it as a PTT, Client Com 8 and CAT Com as Com 108, VFO A, RTS Highlited and Auto Switch TX set to enabled. I don't really see any concrete help out on the Flexradio Community that will help me to get this to work. I have tried to give as much information as I can. Also, when I key the transmitter I get an error message regarding the application.Mark Griffin, KB3Z
