What you've done sounds fine... Do check if you have a rim/rim subfolder somewhere though - for example, when you extracted the files from RIM.rar, perhaps you selected "extract to 'RIM'" instead of "Extract here" and that created a RIM folder, inside which was another RIM folder, and when you moved the 'parent' RIM folder inside bi, the RIM/RIM/data folder didn't sit on top (as it should) the RIM/data folder there. (I hope that makes sense!)

In short, make sure you put the RIM/data folder inside bi/RIM/ (re-install RIM if necessary).
