[Dxbase] PSK31

[JV]

    Need a little help. Trying to setup the PSK31 mode in DXBase2004. I get
the window that says "Invalid Number Of Parameters" no matter what I click. 
Also, there is nothing in the spectrum display window, only a black screen.
Computer is an 800mhz using 98se. Using  RigBlaster and the radio is an
IC-756pro that is linked to the computer. Anyone with some suggestions?
    BTW, N1MM Logger and WinWarbler work OK.
