Error: The license key is invalid

[Shogoki]

Hi
After upgrading plesk from 9.5 to 10, i have an error message

Error: The license key is invalid. In order to use the Panel, please obtain and install a new valid license key.
The amount of currently used resources overrides the limits defined by your license.
The number of websites hosted on the server exceeds the limits defined by your license. You have 1 sites hosted; your license allows hosting only 0 sites.
The number of served e-mail accounts exceeds the limits defined by your license. You have 1 e-mail accounts currently served; your license allows serving only 0 e-mail accounts.

The button "retrieve key" is disabled

How can i update the key

I had a valid key because before i already used plesk 10 on this server (before format)

Is there an ssh command to update key?

I have a server on www.ovh.com

Best regards

I found a solution

For those using ovh
Go to manager -> server -> plesk licence -> erase your old license -> ask for a new one

Weird system but that s work!
