UCASH should have an uninstaller or is a product you can uninstall from there. I don't use that either since RPG infirno has it's own cash/gil system.
Now that you ran the uninstaller try running the installer again for RPG.. If you want rid of it and it is still leaving remnants after the uninstall you should ask for help in the inferno thread or read through it to see if anyone else had similar probs.
