I really want to install this but after losing a whole site last week and starting from scratch i'm not sure.

It's the sql patch i'm more worried about as i really don't want to go into the MySQL section of my control panel and try and remove or alter anything. Backing up and replacing old files isn't a problem.

So a quick question....If i try installing this and something goes wrong or i decide i would rather not use it then how easy is it to uninstall ( imagine i am a novice user )

I already have a full MySQL backup and a full site backup as well as all the site files downloaded onto my desktop.

I would love to install this but like i said i first want to know how easy it is to uninstall ?
