Something is clearly amiss with your PTT and CW configuration. It sounds 
as if you have CONFIG:PTT-KEY set to ON-ON. Set CONFIG:PTT-KEY to 
OFF-OFF to clear the error messages; having done that, you need to 
decide how you will be controlling PTT and configure accordingly.

If you weren't using the microKeyer, the simplest way to control PTT 
would be to use VOX, as Don suggests, and do not configure any PTT in 
N1MM Logger. The second simplest would be to use RTS on the radio 
control port with CONFIG:PTT-KEY set to RTS-OFF, but I don't think this 
works with the microKeyer. The microHam setup instructions show how to 
configure both MMTTY and MMVARI for FSK and AFSK. Note that even if you 
configure N1MM to use RTS on the radio control port for PTT, that is 
intercepted by the MKII and not passed through to the radio. You need to 
leave the K3's CONFIG:PTT-KEY = OFF-OFF and let the MKII do PTT control 
through the ACC connector or the PTT IN jack on the K3 (depending on 
which cable set you have).

Do not configure N1MM to use software PTT commands with the K3; 
regardless of whether you are using a microKeyer or not, there are 
better more reliable alternatives available.
