Made ROM from kitchen and getting error with HTC applications?

[leadpoizon]

I used a kitchen to make my ROM, but i'm surely missing some file, because whenever I try to launch the HTC calculator or the HTC YouTube application from the start menu, I get an error:

"The file 'htcCalculator' 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."

I know I'm missing some package or file, but would someone happen to know what it is?
