By using Direct cd, does this mean your using easy cd creator aswell?
You say you deleted the folders....didn't use Uninstall?
By just deleting the folders it won't get rid of it, as there is all kinds of sh*t in places like the registry.
Have you tried adaptec website & downloaded the newest updates & stuff??? they should install over the top of the earlier version
Also you could try using
Regcleaner to try to identify & delete any registry settings for Direct cd
Other than that.....
