Thank you for reporting the issue.
Could you please check if the license file is successfully stored in the App_Data\Sitefinity\ directory? If it is not, then it might be a file-access permission issue.
Otherwise, we will be glad to inspect your project locally, and check what the problem might be. Is this an option?
All the best,
the Telerik team
