Hey David,
The Forecaster sample data should be loaded with every client install. It's usually an Access DB file located at C:\Users\username\AppData\Local\Microsoft\Forecaster\demo70.mdb. To log into it you enter the username of adm without a password.
If your access database is empty that would be odd and I would think I could send you mine or a re-install of Forecaster should add the good original back.
If you are looking for the sample data that goes with the books I can send that as well but would need your email address.
Thanks!
