When I want to go to "Locations" under Courier, I get this exception:

I've a license for "exsilent.com", and my dev environment is setup with "dev.exsilent.com", so it should be validated. I also checked at the "revisions" node in courier, and it doesn't say my domain is invalid for the license. I have this in courier.config as repository:

 <repository name="https://exsilent.com" alias="Exsilent Production" type="CourierWebserviceRepositoryProvider" visible="true">

      <url>https://exsilent.com</url>;

      <login>*******</login>

      <password>******</password>

      <passwordEncoding>Hashed</passwordEncoding>

    </repository>
