828 MK2 FW (master) + 8pre (ADAT) + Ableton config problems

[laneo]

Hi all,
I have my 828 mk2 conected via FW to my iMac.
The 8pre is conected with an optical cable to the mk2 input.
In CUE Mix everything seems to be properly connected. I can see the 8 ADAT inputs from the 8pre, and those inputs works as expected.
Here´s the problem:
1- If I open audio preferences in Maschine (standalone version), it doesn´t show any of the ADAT inputs.
2- In ableton live,the ADAT inputs are there, but when I try to record something from any of those inputs, every input from the mk2 is also being recorded. Its like any adat input is the SUM of that input + everything from the mk2.

Any ideas? Does anyone has a similar working setup?
I´m in maverick btw.
Thanks

Just in case anywone is interested, this problem only happens in BUS 1.
So i had to mute everything in Bus 1 and use Bus 2 for the main out.
