Is mocking those who have problems with your plugin really the best way to promote it? Who knows what charlls has dedicated to? Also, I wasn't saying it takes a programmer to set it up, I was merely stating what I did to say that my problems aren't because I don't know how to find the plugins directory.
I've seen it in action, so I know somebodies gotten it to work. I had high hopes for it too, because it looks like a good option, but sadly the only option. However I have not had it work without problems in any environment I've set it up in, so I'm giving my honest opinion. I've often seen in your forums that Shayne feels the best solution to almost every problem posted is to upgrade either wp ecommerce to a beta copy, or upgrade WordPress to a beta copy.
From google: BETA - second in order of importance; "the candidate, considered a beta male, was perceived to be unable to lead his party to victory"
Hardly a solution for anybody running a production environment.
