[Dx4win] What am I doing wrong now?

[Tom Horton]

I am trying to set up the CW keyboard but when I try to open it,  I get a message that Cw port 3 is already or or it can't connect. 
 Rebooted... no help
 powered the computer down...no help
 unplugged and replugged the keyer.
I am using Winkeyer USB.
It is bound to be something really stupid.
I think I have the keyer set up in the preferences correctly.
