Set incorrect "All Router" SNMP community string... how to change?

Set incorrect "All Router" SNMP community string... how to change?

When installing Netflow Analyzer I set an incorrect SNMP community string. Now, the global setting for "All Routers" is incorrect. If I click Set SNMP and try to change the community string for All Routers it says "Please enter the new Router name". Is there any way to change the SNMP community string already set up for the All Routers router name??
