I recently got a new TI89 (Titanium v3 hardware) and experienced the same transfer issues. I was using Ubuntu edgy eft (7.04) and wordrider would hang. I upgraded to gutsy gibbon (7.10) and wordrider suddenly worked. Also, I grouped the file using gfm (Group File Manager), which should be available for Mac OSX as well. Grouping the file allowed the transfer to go through.by kevinality - WordRider Bugs
