No I use this myself on several production sites, probably for almost a year. No problems.
You've never posted any details of what "doesn't work"... so without more details, I don't really have any answers other than start again with a clean copy of the scripts and make sure you got all the steps.
95% of the problems with hacks, (and this happens when I install them as well) are problems with doing all the steps. When I have trouble.... first I backup and try again and make sure I did't miss a step.
Then if that still doesn't work, then I suspect a conflict with another hack... so then I try with a clean "out of the box" copy of the scripts. That usually helps me narrow it down.
