Try unzipping with WinRAR or some other authoritative extractor. I have found you can name the folder anything you want. Just keep all the extracted files, and be sure to put the folder that they are in, into the "dic" folder in the main folder you see when you connect your N900 to your computer via the USB cable. That should do it.
