I tried re-installing my instance of SSRS, re-setting up the WebService URLs, creating a new ReportServer database in SQL Server and configuring the Report Server database credentials in the `Report Server Configuration Manager`. This didn't work.
I also tried going into the `users` and `policyuserrole` tables in the `ReportServer` database and manually added my account and SSRS roles to it. This didn't work.
The Report Manager url doesn't allow me access anything or make security changes.
My account is inside the Administrators group which has access in the database.
