Sentinel LDK with HASP4 session and client logging

We have a red HASP HL USB license key connected to a:

licensing server (2K8 R2)

Clients are Win7 Pro x64

HASP License Manager V 8.32.5.40

Sentinel LDK Runtime Environment V 7.41

The ACC displays the key and it's details however, there does not appear to be any indication when a client machine checks out a licence. No session activity or user and no activity regarding a 'user@client' in the access log. Must be doing something wrong!
