SQL Server Reporting Services Data Analysis Reports

Hello,

I'm trying to run a "SQL Server Reporting Services Data Analysis Reports", let say "Storage Summary" for example, it ask me to state the "Site Name", but the dropbox as no value and I can't write any, in the other hand in the "SQL Server Reporting Services Operation Reports" all the report I run as have the "Site Name" correctly filled. What I need to do to fix the problem? 

If I use the administration Console's to access the Enterprise Vault Reporting's reports, I'm forwarded  to an old server, where can I correct this?

Best regards

António Mourão
