Why MS Access is showing blank environment in runtime!

I've made a little progress with packaging and making a runtime file for my Access 2007 app using Microsoft info pages. But for some reason, I'm getting a blank application when I test-package it and then tried and run the file.
Basically, I created a private certificate using Office Tools, did a "package and sign" inside Access, then (as advised by MS) changed the file extensions to .accdr, created a shortcut and edited the shortcut executable so that it had /runtime at the end.
What actually happened is that it opened up a blank environment, but with the Acrobat tab of the Office 2007 there is a ribbon showing (and nothing else). (I have Acrobat 9 Pro installed). No idea why.
What I want it to do (at the moment) is open up one of the forms by default, so users can enter information-or even better, open up multiple forms together.
In the Access Options for the database I set it to open the desired form by default, under Current Database options and then I did a Package & Sign again. However it still comes up blank, whether or not I run the .accdr file, or accdb with /runtime.
Any idea how I can fix this?
