WMS 5 - failed to check in: licence is expired

Hi,

Just upgraded from WMS 4.0 HF3 --> 4.2 --> 4.3 finally to 5.0

Everything appeared to go ok and our existing devices talk to NMS without issue however for any new thin client (optiplex 3000 thinos) i see an error on the device "wms: failed to check-in: licence is expired" and the device fails to register in WMS and get policy.

Running WMS standard and installed the Key as part of the upgrade.

Anyone come across this?
