MC Control always disconnecting, no sync, offline

[RaToX]

Dear colleagues, i kindly seek your help!
I bought a MC Control surface which, in my dreams, was perfect, but it was a very bitter first-day run:

0) i have a new iMac 27' core i7 10.6.6 i have LATEST euphonic software 2.5.7
1) i was able to connect the MC Control to the network, had some problem with DHCP mode but in manual address mode it got connected
2) the finder is controlled without problems, and macros and keyboard combinations works very well. also application switching and many more less useful functions for music:)

--- this means that the network is connected, at least for controller ----> computer
--- all this functions that are working implies no feedback to the device (like moving fader or light-up of buttons----

the tragedy is:

3) if i use for example a FADER to control in volume pro tools 9.0.1 or logic 9.3.1happens ALWAYS the following behavior:

3a) the volume in the DAW is changing accordingly to my fader movement
3b) the volume level in the Controller Display is NOT changing
3c) after i release the touch control of the fader, since the internal state of fader is not changed (the volume label in the mc control is not changed) THE FADER IS PUSHED BACK IN THE OLD POSITION AUTOMATICALLY
3d) THE UNIT GOES OFFLINE and gets back to the "Welcome to artists series..etc.."
3e) at this point is impossible to communicate with the DAW (logic or pt).

----- this applies to faders, knobs, track names (if i change in DAW it's not updated in the controller) and other controls that implies a bi-directional communication

4) i can recover getting back to a basic applications like the finder and then going back to the daw, the connections then is restored, but as long as i move a fader all the sequence of problems is repeated exactly:

basically then: when i do simple things that involves no level change or audio interaction everything goes well (use the touch screen to place markers, copy files in finder…trash items) everything goes well. when i do audio stuff that implies an advanced communication the controller goes offline!

Please help!
