Ok, I tried it again and just got this error: Error reading from file: d:data\offline\ca21f9c0\68589853\effectmesh_humanbody.mesh. Verify that the file exists and that you can access it. What would cause this?

I am trying to install the game, but I keep getting this error: Error reading from file: d:data\offline\ca21f9c0\68589853\effectship_psicolonypod.mesh. Verify that the file exists and that you can access it. Can anyone help me with this? I run Vista and am logged in as the administrator.
