im having touble uninstalling CS2 after it installed incorrectly

i have been using illustrator 10 & CS5 photoshop trial version fine on my windows vista (illustrator for 2 yrs on this computer). i got CS2 so i uninstalled both programs before installing the CS2. after installing i never got a finished window & it just closed. when i tried to open illustrator & indesign it closed as soon as it finished opening. photoshop did ask for registration info & then shut down/closed as well. i tired to uninstall from program/features in control panel but it doesn't work, it doesn't prompt me to do anything so adobe help had me install the windows installer clean up utility to remove programs not installed correctly. they are still not uninstalled & when i tried to reinstall the 1st cd gets to initializing & then stops. i now have removed all the adobe folders from my c drive & still cannot remove. i need to reinstall - HELP!!!! thankyou.
