Did you use the SNMP Tool that you can download on the PRTG website and test this?
Sounds like there is some mismatch in your configuration. Probably the password wasn't transferred or needs to be reset or something like that.
You find it here - you might wanna use the PRTG Probe-Device for testing, to be on the same IP address assuming there might be restrictions in regards to IPs as well.

PS: You might wanna do a DEBUG SNMP or similar on the Cisco device as well - there is a good chance you see what is the issue. I still would just overwrite the SNMP password and double check that the config has the correct values. Pretty common that issue is that either the running config wasn't saved on the flash (copy run start) or no good backup was in place - where I recommend things like CATTools or similar and constantly backup the running-config - what is the current config... the startup-config might be outdated..
