Reason 2.5 To Dp 4.12 Through Rewire, Can't get a sound Options

[jungledas]

HI,
Anyone using both DP and Reason could help me figure out why i can't hear the reason song in DP.
I did everything the manual said:
selected the reason channel (mono or stereo) in the input menu of the audio tracks, then armed it.
Checked "always"in the input monitoring mode option from the setup menu.
as well as the Audio Patch thru in the Studio Menu.
Both apps are synch when I hit play.
The rewire is working fine, I get a signal in the reason device when I play my keyboard, but no sound at all.
The strange thing is that the song is recorded in DP when I hit the record button, but I can't hear it while recording. Just playing it afterward.
Any hint, please?
