Owncube Activation Email Problem

I got late to activate my OwnCube account and now i can’t create a new one. The massage on the activation page was:
Error

  • The token is expired, please contact your provider
    Is there a way that i can get a new activation email?

sorry, please contact the support of your provider. We can’t help you with their setup and if they need help, there is the enterprise support for that.
