That is a clientexec screen and shows that your account is pending. At the point they activate and authorise your account I'm sure they will send you instructions on how to access your control panel and create accounts.
I agree with Martie. Your host should be able to provide you with support on how to use all of these features, and if they are not i may suggest you move to someone else who can actually provide you with support on easy things like this.
Because you cannot set permissions for resellers in Client exec it is set to manually account creation and activation.
Accounts are usually setup within 6-12hours
Im Sorry for any confusions, but we can't have resellers with root access.
