I've made the error retry loops go back as far as the input menus. Split all the pathname inputs into 2 pieces (base directory and set directory). Reduced the size of some fixed strings. Stopped the install aborting if ftp can't find a set (eg the X ones). The French and Polish transations don't differenciate between Base_dir and Set_dir - but that can be fixed later.
