Indeed, we found a problem with the installation of the first release of the Reporting tool - it will not uninstall the beta automatically, and once installed, it will mess up the beta installation. We are working on a new installer as we speak and we will update the downloadable files as soon as all cases have been tested (CTP, CTP2, Beta1 and Beta2).
For all of you who have not installed the official release yet but have used the beta, please UNINSTALL the beta first! For the rest of you who have installation problems, we will provide detailed instructions on how to clean up the old installations and install the official release.
We are deeply sorry for the inconvenience caused. We will be investigating how this problem passed through our stringent tests once we release the new version.
