How to Customize a Custom Rom: Adding/Removing Programs

[kbl]

I ran PrepIt.bat on NFSFAN's latest rom as I would like to customize further. After that finished, as a test I ran BuildOS.exe and then BuildIt.bat. Everything completed properly as far as I can tell.

When I flash this ROM, looks like everything is fine... but for some reason I can't get some applications to work (and yes, they work in the donor ROM). In this case, when I try to run the camera application it says:

"The file 'Camera' cannot be opened. Either it is not signed with a trusted certificate, or one of its components cannot be found. If the problem persists, try reinstalling or restoring this file."

So, all I did was dump and recook... no changes. So I have no clue why the camera app is no longer working... Any ideas?
