bought license but it says it expired

[carlosho17]

Hi

I've running a Plesk 8.0.1 FreeBSD server for several years now for which I bought an unlimited license, and all of a sudden I got this message when logged as admin in the Control Panel:

Warning: You are currently operating within the grace period of your product license (PLSK.00025085.0022). To update your product license use the Retrieve Keys function of License Manager.

When I try "Retrieve Keys" under "License Manager" all I get is a blank screen.

I cannot open a support ticket , as I don't have a support contract active.

Can anyone help ? This is very awkward, as the license we paid for was supposed to never expire.

Thanks in advance,

Carlos
