Cross DJ SOFTWERE ISSUES - URGENT!

Dears,
I am experiencing some issues with the software.
I am playng with the INTERNAL MIXER MODE using the settings listed on the manual (as I always did in the last years).
This time ther's something weird going on:
-If i use the settings listed on the manual (OUTPUT 1: U-Mix Control Pro 1/U-Mix Control Pro 2 // OUTPUT 2 U-Mix Control Pro 3/U-Mix Control Pro 4) I have the audio working fine in speakers -ut i've no pre-listen.
-if i use the settings (OUTPUT 1: U-Mix Control Pro 3/U-Mix Control Pro 4// OUTPUT 2 U-Mix Control Pro 1/U-Mix Control Pro 2) I have audio signal arriving to my headphonse but none into the speakers.
I can also control the volume in my headphones using the controller's dec controls of the traks. And this is quite weird.
Hope i've been clear enough and I really hope you can help me asap...
Thsnks in advance!
