[Elecraft] PSK31 help

[Jay & Jac]

Need some advice... I wanted to try listening to PSK so I downloaded
digipan for a 2 week free trial and plugged my sound card into the earphone
plug on the K2.  

I can't seem to make the digipan show a waterfall view...In the current
view, I'm receiving on the upper window and the lower window looks like it
is the transmit window.

Question:  What do I push to copy PSK, where do I find it on 20/40 meters
(what Sideband or CW?) and how do I get the waterfall display to work?
Currently it's copying noise very well, but noise is noise.
