Ah, the wondrous Mac OS. I enjoy simply dragging a folder to the trash and removing the program with ease rather than running an uninstaller (i.e. with Windows) and trying to decide whether a DLL file that's not in use is safe to delete, or reading the report that the folder has to be deleted manually, etc.
Also, if you drag the folder to the trash and are still worried about some files scattered about on your drive (like fulmer suggested there might be), you don't need to worry about them harming your computer. You might try checking the extensions folder and control panels, and if you see anything that you know for sure came with the program, you could try moving it to the "extensions (disabled)" or "control panels (disabled)" folder. The next time you restart, if everything works fine, you should be safe to trash the files.
