ECM Nagra 1810 bad times

hi, last days 1810 sends high sbox + cccam times since, as a result cuts and freezes. Anyone know what's happening?

New Revision Rom nagra card.

Before changing channels and groups now ECM changes on all at once, in the same second;this gives high times, cuts and freezeos, or have limited sids. Now expect some solution sbox or oscam.

4 sids-->0.250-0.800 ms
8 sids at the same time--->1.200-2.000 msg
16 sids at the same time---> up to 3.000 msg aproximate
