Thank you Ko12upted,
Now i see that my problem with BO2 and LINK is related to TU.
I have downloaded all the 3 TUs using FSD and applied the most recent one but it´s not working. My multiplayer menu shows 7.0-1.
Does anyone have any idea why my TUs are not being applied? My game was placed external (USB01:) and in the GOD format.
Edit1.: I checked with file explorer that "HDD1:/content/titleid/0000b000" has the TU file downloaded by F3. 8((
