PWD & Data Report

I've been working on a database through DAO code, which works fine. I now added a couple of reports through Data Environment and Data Report. My problem is, it works fine on my developing machine, even using the setup package to install in different directory. When I install on a clean pc, the reports show blank white with failed to get recordsource. I believe I need to reference something or include something that PDW isn't doing. Still a beginner, and trying to figure it out! Thanks to anyone that can help in advance..
