Actually, I installed it on 4 different computers, and on 1 I did have a problem. It was a long time ago though, and don't remember what the exact problem was. But it is a pretty cool plugin. Back in the day, there was really nothing quite like it around. I'd say try getting it to work again (even check for updates, AnalogX still has a web page). I first used it after hearing a really fast chopped up vocal bit (Almost hard tremolo, but more extreme). I tried replicating the idea a bunch of different ways, and until I found this plugin the only good results I had, were made by chopping bits out of the wave file, or using volume automation (a whole lot of extra work compared to popping in the plugin, and adjusting the sliders to taste). Brilliant!!!!
