MSSQL Monitors Not Working

I am trying to setup MSSQL monitors and am not having any success. I think the problem is that SNMP monitoring is not working on the OPManager side. When I test the credentials the SNMP works. However when I try to test my specific MSSQL monitor that is SNMP it is not able to connect.

I followed these instructions http://support.opmanager.com/sd/AddSolution.sd?solID=10501 and in the MIB browser I get this error:

Sent get request to localhost : 161
No data available in this sub-tree

I have verified that port 161 is listening using Microsoft's PortQuery 2.0 tool. Here is the output from that:

C:\PortQryV2>portqry -n 127.0.0.1 -e 161 -p udp -cn !public!
