APC UPS with Powerchute Agent not working after upgrade

[gduck]

I have an APC Smart UPS 2200 (SMT2200I). UPS connected to PC with USB cable and use Powerchute agent and enabled SNMP trap.

After upgrade firmware from 3.8 to 4.2, UPS SNMP comminucation not working.

before: UPS communication working over SNMP. And I see these protocol setting in UPS settings: "APC UPS with SNMP management"
after: UPS communication not working over SNMP. And I don't see SNMP protocol setting.

Any idea?

THANKS!
