Two things come to mind. First, security - do you have read (select) access to the fact table? Second, your star schema model - are things joined correctly?
To verify the star, you could start by rebuilding it from scratch, starting with the fact table and a time dimension, then add the other dimensions one at a time.

The reasonable man adapts himself to the world. The unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man. - George Bernard Shaw
