diskeeper's trial ran up cause the stupid crack didn't work
 

and when i try reinstalling it with a different crack, it will not even let me defrag. :(

how do i "flush" the memory so that my computer thinks diskeeper has never been installed before.

You'll have to remove most or all traces of it in the registry.

and exactly how do i find those

Uninstall and run CCleaner. Do both the cleaner and the issues scans.
