Set Proper IP Address for License

Hi everybody. First of all sorry for my english, long time withot talking, and i don't know if i'm posting this threat on correct forum.

Well, i'm not a sys admin, just somebody who are learning how to administrate all my sites in a dedicate server.

Yesterday, after 3 months all working good, i got the msg: Cannot Read License File

I made everything that cPanel recomend:

• To ensure that the server is licensed, navigate to cPanel & WHM License Verification | cPanel Inc., and enter the server’s public IP address. My ip is licensed.
  IMG: prntscr.com/a2nll2
  
  
• If the server is licensed, run the/usr/local/cpanel/cpkeyclt command as the rootuser.
  Done and i get that the license is expired, but the IP is another one that mine primary.

I contacted with OVH and they can't give an answer (gooood!) and cPanel told me what i know, that my my primary IP is licensed but the IP that is "sended" is this another one where i don't have any license.

OMG!! What can i do? How i can change this IP? How can i define my main IP as main?

Thank you all for your help.
