IBM Licencing Server v8 - Cannot run tests from RQM 4.0 or Performance Manager 8.1

I have had these 2 programs installed and pointing to my Windows v8 Licence Server and running for the past 18 months and now i cannot execute any tests from either.
I can login to RFT on any of my 8 machines and then use RQM to schedule an automated test but the RQM automated run stops a few mins later.
I can login to RPT but as soon as i run a performance test i get an error message 'NO licence keys available for 100 user run ' even though i have 1000+ virtual users.
Any ideas on why some licences are orange and show V7?

Here is the licence server status:
