vShield Endpoint and Deep Security v8 SP1

Hi,

I am running ESX 4.1 and I installed vShield Endpoint 5.01.  I am trying to install Deep Security 8.0 SP1.  After I prepare my ESX host, I get a vShield Endpoint alarm "vShield Endpoint Host Status" and I get the error message "Lost communication with ESX module" in the vShield Endpoint tab in vCenter.  My dsva activates fine and vShield is shown as installed and registered in Deep Security Manager.   The problem is that the anti-malware engine goes offline on my VMs.  I installed the vShield driver using the latest vmware tools.  Any help would be very appreciated.  Thanks.
