Pogo Cheats Qusetion?

Is there a way to uninstall a trial cheat and reuse it again without reformatting my hard drive? I am wondering if I have to remove files or what to do. I tried to reinstall after use and it still says trial period up... please purchase. In the past after reformatting I have downloaded it again and no problems. Could you please be very specific and give detail , Thanks. Or if there is a token dumper or a cheat that kicks *** pleezzzeee let me know.
