Problem here while activating the terminal bundle from Intel

I have a problem here while activating the terminal bundle from Intel. I get an error message like this –

Key sequence C-p t starts with non-prefix key C-p Is that looking for C-P to turn into a prefix command ?

I am confused. Though C-p is bound to previous-line by automatic in emacs and unix shell environment, so is there any other prefix which can work better ? I am using ubuntu operating system and my emacs version is 23.3.1.

The following bundle is activated – (Accessibility completion css cucumber diff erlang git html java javascript lisp markdown power-edit python ruby haml-and-sass yaml snippets xml terminal)
