My CCE has stopped working correctly

Anyone know were I can find DialogsU.DLL....I just when thru and "made room" on my HD and deleted the Pinnacle folder and and someothers too. I also just installed Cole's codac pack too..now my encoder isn't working ..I vaguly recall a bundle of .dll's from somewhere.

more investigation reveals the following: Anyone with a pinnacle product like Liquid installed on their puter May experience .dll errors when opening CCE after uninstalling said Pinnacle product..the following pinnacle .dll's will be missing:
vfmpegu.dll, dialogsu.dll, fileiou.dll, futilu.dll, gbtoolsu.dll, setfileu.dll, vafxu.dll. What I want to know is why this happens...CCE thinks it needs these? Anyway, I've reinstalled Liquid and am now backing up these .dll( found in Windows\System32) then uninstalling again.
