I notice the following error in the services-messages.log file

[DEBUG] [6/23/10 9:35:46 AM] [] [Registration Web Service] [] [registerDevice complete, time: 19ms, code: -30, device: xyz..., thread: 72] [] []
[DEBUG] [6/23/10 9:36:06 AM] [] [[[UM Inventory]]] [] [getLicenseService: got LicensingAdminService] [] []
[DEBUG] [6/23/10 9:36:06 AM] [] [[[UM Inventory]]] [] [have LicensingAdminService] [] []
[DEBUG] [6/23/10 9:36:06 AM] [] [[[UM Inventory]]] [] [license is expired] [] []

Our licensing setup looks as follows:
Product Licensing
ZENworks 10 Asset Management : Active
ZENworks 10 Configuration Management : Active
Asset Inventory for Unix/Linux : Expired

Not sure why the above is indicated as expired. I have scheduled reports to be emailed to me and am getting nothing back.
