Wholehog 3 - No output

Hello to all,

Just a few days ago I was load show which has been maked in software version 3.2.1 show includes one dp8000.
On my desk I have software version 3.1.9 and dp 2000.

After that desk no longer gives DMX output, neither in dp2000, neither on the desk outputs(left touchscreen).
Now we have downgrade to ver.2.5.0 and only in that version outputs working fine.
We have been trying to do full install to 3.1.9. and same situation appears. NO DMX AT ALL
