Hacking How do I uninstall cwcheat?

[AncientBoi]

I have an old version of CwCheats on my PSP and wish to upgrade it to the newest version 2.2 REVD [I believe is the newest] available. I intend to create the cheats on my own, as some of the ones in the downloaded DB's keeps crashing my PSP. Thus How do I uninstall it? I might have it on permanent when I installed it the first time. Then I can get to work with the artmoney.
