what can I do? Can someone solve this issue? I can't access to the server from Centova's Control Panel, neither suspend or activate it..

Check your logs (or restart Centova Cast) to find out what the licensing error is, then fix whatever problem indicates is going on.

The message in the web interface is intentionally vague to avoid letting your clients know the details (eg: it could be embarrassing for a company if their clients found out they let their license get suspended for nonpayment, etc.)

Ok it's a license problem, the trial version expired on 4th October and Centova still worked fine until yesterday. I've already bought a new individual annual license (on 3rd October). Is there some way to 'upgrade' the license key without having to reinstall everything!?

Here it is...

  License certificate expired; need an update from the Centova Technologies licensing servers.

So, the Account Package is #108651, and it's ACTIVE and PAID on 3rd October 2012, and it expires on 10.03.2013. What can I do?

Did you try to re-issue the license? I have just installed a fresh server I do not think there is a problem with the license servers, go into your Centova.com account and click re-issue license and try again

Can't find a 'reissue license' bottom in my account 

Anyway, here is a licensing test I made a few seconds ago but I'm still stucked..

Edit /usr/local/centovacast/etc/license.conf with your key

Restart centovacast using /etc/init.d/centovacast restart

thank you, solved
