Problen in distributing Policy

Hi,

We have recently upgraded to F-Secure Policy Manager 14.01. Now we are facing some problems. We have approx  5000 clients reporting to FSPM 14.01. We have set the Proxy Update server also. Now, when I am changing the Proxy Update Server Address in Setting Tab and distribute the Policy than Policy distribution is not taking place. For a while server shows---waiting for server and after that Plocy distribution icon remain highlight in blue colour. When I tried to distribute the policy again than the same thing is happening. Please advice.........
