Not sure what the fonts stuff is...are you sure you downloaded the correct version? Go here
http://www.octopus-studio.com/download.en.htm and download the ARM HPCPRO cpu version. It is a zipped file. Just copy all the contents to any folder on your 900C. I created a folder called MDICT in the program files folder. I then copied over one of the dictionaries, the opted003.mdx file into the same folder, but it could have been anywhere really...and the program runs fine.
I didn't have to do anything with any fonts...which I guess is why I am confused at your problems....
