Are you saving your data in an appropriate filetype (presumably SAS data set) in the AutoLoad filesystem folder. Autoload will only load certain file types from a filesystem folder - SAS data sets, Excel spreadsheets, CSV & delimeted files.
(Forgetting data builder for a moment..) what happens if you just place a SAS table or CSV file in the AutoLoad folder?
Have you turned the AutoLoad scheduler on?
If you are using DataBuilder, do you even need to go via AutoLoad? Why not simply schedule the Query and have it load directly into a LASR library?
Please clarify your requirements - then maybe we can help clarify if the best solution is DataBuilder, AutoLoad and/or a combination of both.
