Matty7 - you're looking for spell correction in Italian ? It is almost certainly fixable.
I fixed spell checking for French on a 64bit UbuntuStudio desktop using Scrivener 220.127.116.11 very easily see this thread : viewtopic.php?f=33&t=33533
You need to have Aspell installed on your linux system including the libaspell-dev package and then copy the italian .rws files from the aspell system location to the correct directory in the scrivener installation.
I also did the same on an old Debian laptop (32 bits) also using scriv 18.104.22.168.
If the simple fix in the above quoted thread doesn't work for you, check out some other spell checker threads on this forum.
