Crystal Report Server 2008 - Schedule/Process/History Grayed Out on CMC

Hi - I'm using Crystal Reports Server 2008 (11.5) and am unable to schedule reports - the schedule (as well as the Process and History) tabs are greyed out in the Central Management Console and don't appear at all in Infoview. In addition I can specify the database when I setup a new report or when using the Publishing Wizard to import files I don't get the dialogue about scheduling.

Am I missing something?

Thanks
