If I am correct, the problem you are encountering is due to the fact that you cannot select a user so that you can continue with the setup of the analytics module? If that is so, can you check whether you have more than one membership providers enabled because we have encountered similar reports when having more than one active membership providers.
All the best,
the Telerik team
