This copy of vBSEO is unregistered and expired

Hello,

since this morning we are not able to access our site:
http://www.kristallpalast.net

We are not able to access vbseocp.php, as well.
No changes were made before this error appeared. While trying to access our site we get following error message:
[ This copy of vBSEO is unregistered and expired ]

We purchased our license about January´06.
We would be pleased, if you can have a short look on this problem.

Hello Thorsten,

please make sure that you have entered the license key in vbseocp (you will find the key on the same page at vbseocp).

Hello Oleg,

where can I find the lincence number in the vbseocp.php?
I´ve searched the whole CP but didn´t find any oppurnity to enter the licence number, neither did I find the licence number.

Anyway the site works now again.

Thanks and Greets
Thorsten

Hello Thorsten,

it is located at the top right part of vbseocp page ("Your vBSEO License Key").
