I had some problem with my SQL Server 2005 and decided to uninstall it. It wasn't successful until I tried out some steps found from the internet and it was really "cleaned up".

However, when I reinstall the SQL Server 2005 Express again, I followed the same steps given by the Microsoft demo video downloaded from their website, the report server refuse to run now:


What shall I do now? any idea what do I need to reconfigure in order to make it work? I tried reinstalling/uninstalling SQL Server 2005 express several times but the same error still occur......
