Report Builder will not launch

I am having problems launching the Report Builder. I click the button and nothing happens. I did see the other suggestions about re-installing the .NET 2.0 Framework but that did not help. I tried to launch it directly from the address bar and I am getting the same reponse as when I click on the Report Builder button. I can access the Report Builder from other machines and it works fine. I did just recently install IE 7 and I tried to uninstall it and go back to IE 6 but I got the same results.

Any help would be appreciated.

Thanks Tim

Does navigating to http://localhost/ReportServer/ReportBuilder/ReportBuilderLocalIntranet.application work? Try adding localhost to trusted sites.|||

I tried using this link http://localhost/ReportServer/ReportBuilder/ReportBuilderLocalIntranet.application and adding it to trusted sites and it did not work. Maybe I have some corrupted or missing files on my machine. Does anyone know what files I could possibly delete to make Reporting Services think I have never launched the Report Builder and have it re-update my machine.
