Getting the error below	IM works, CSF device does not. Any Ideas?

Jeff,

This community does not provide technical support and is not staffed with technical support experts. I recommend you post this and future technical support questions to the Cisco Support Community (https://supportforums.cisco.com/index.jspa) where our Cisco technical support experts provide assistance. Another option is to open a ticket with the Cisco Technical Assistance Center (www.cisco.com/go/support) to get expert debugging assistance.

We hope to hear from you again.
