I stopped using that monstrous thing after it crashed one of my sites. Now I use QuickCache for WordPress ( I’ve been using it for about a year and a half with no problems). It’s free, works brilliantly and is updated regularly. I actually just updated my plugin with no problems at all. This is the link to the developers’ website/plugin if you would like to try it (just scroll down the list of plugins and it should be fifth in the list):
