Can't uninstall trial CS4-Extended.

Hi,

I downloaded a trial version of Adobe CS4 Extended from Adobe's site, at the end of the trial period I decided to uninstall the software. I am now in the position of having some drivers in the 'common files' folder which seem to be stuck there permanently. Whenever I try to delete them it says 'Destination folder access denied - you need permission to perform this action', I have tried all the different admin settings I can find but with no luck getting rid of them. Even in safe mode it is still the same. I really want to avoid having to reinstall Vista. Also CCleaner and regedit, tried everyhting I can think of.

These are the files: Common files - Adobe -

(Adobe Version Cue CS4 - folder)
ADFSMenu.dll
AdobeDriveCS4_NP.dll
BIB.dll

(Adobe Drive CS4 - folder)
VersionCue.dll

Thank you for any advice you may be able to offer me with this.
