Emacs: file-error "Cannot open load file" "cc-mode"

[Magnus Mager]

Hi there!

I'am using GNU-Emacs 21.2 on both my home machine and my notebook.
On my host machine it works fine, but on my notebook the following fails:
- When I open an c/cpp file the status line says: file-error "Cannot open 
load file" "cc-mode".
- When I want to switch into the gnus mode it says: Cannot open load file: 
gnus.

What have I done wrong duiring installation?


Thanks.

Magnus
