problem with vbox

i just installed puel version while i had ose installed, is that a problem?
when i try to run a vm the screen comes but goes and give this error:

Failed to open a session for the virtual machine win1.
Unable to load R3 module /usr/lib/virtualbox/VBoxDD.so (VBoxDD) (VERR_FILE_NOT_FOUND).
Unknown error creating VM (VERR_FILE_NOT_FOUND).

so should i uninstall both and install puel?

edit: it worked! gr8! thx u all guyz! problem solved!
