Netflow and HPSIM Agents

I have an issue I was hoping someone out there has seen. We have Netflow Analyzer 6.0.0SP2 running on a HP Proliant DL385 G1 running W2k3 SP2. The server was built without the normal HP Systems Insight Manager Agents installed. Upon installing version 8.11a of the Proliant Service Pack, Netflow was somehow damaged. The icons on the Start Menu disappeared but the group is still there. We also lost the icon in the system tray that shows Netflow running. The service dropped itself a couple of times but it starts right back up.

Has anyone seen this and have any advice. Adventnet tells us to reinstall but I don't think the install is damaged.

TIA!
