Answer 1

I get this a lot. E.g if you have sub reports only, it thinks the main report is blank. You have to do something silly like insert a dummy SQL into your report such as "select 1" then populate a hidden part of the report with the result. When it works on in report studio, but gives you the report is empty on the server (with a good data source - other reports working) is when you have real trouble. Not solved those yet.
