Ryskia, I would start from scratch.  As I understand it, as long as you don't RUN the game from the CD, SuckuRom won't be installed.  You should get a noCD.exe for it, after you install everything.

Someone please correct me if I'm wrong about this.

Make sure if you use the grid cheat you change it back to "true" when you're done (boolprop snapobjectstogrid true), or you'll have a heck of a time placing things.  I find this cheat especially useful for coffee tables.
