Of course we can help you. It would be easiest if you called, but we can do it here too if, for example, you are in another country and calling would be expensive.
The manual for your PMAC2A-PC/104 is here:

The software setup starts on page 15. There are only a few variables you need to configure in order to use the Filtered PWM DAC outputs. Below is an example set of settings when using motor 1:
I900 = 1001 ; PWM frequency 29.4kHz, PWM 1-4
I901 = 5 ; Phase Clock 9.8059kHz
I902 = 3 ; Servo frequency 2.451kHz
I903 = 1746 ; ADC frequency
I906 = 1001 ; PWM frequency 29.4kHz, PWM 5-8
I907 = 1746 ; ADC frequency
I916 = 0 ; Output mode: PWM for channel 1
I169 = 1001 ; DAC limit 10Vdc for motor 1
I10 = 3421867 ; Servo interrupt time
I100 = 1 ; Enable motor 1
Make sure you have these and then let us know if you have any other specific problems. Show screenshots of your motor status window and tuning windows (from Step Move and Parabolic Move) if you can.
Note that you can use the newer PeWin32Pro2 for setup also. It's available here:

It might be easier to use than the older softwares.
