I've installed various versions of Fab Decrypter on several different computers over the past couple of years and it's always worked flawlessly. However, I just installed it on my nephew's computer (which is identical to mine as I built both at the same time) and I get the dreaded "this program has performed an illegal operation and must close" message. The same version of Fab works great on other computers, regardless of operating system. I know it works well with Win XP and Win 98 SE. I cleaned and defragged the registry and re-installed Fab, but nothing works. If you know of a cure, please email me at email@example.com. I'd appreciate any help. Thanks.
