I've been trying to import into Trados Studio 2011/2014 a TMX memory I generated through Wordfast.

After creating a new, empty memory and trying to import my TMX file, I always get this same error message: "Positive number required. Parameter name: culture". I've read posts saying this has to do with the languages specified at the beginning of the TMX. This is a Portuguese to German memory, and the data at the beginning reads:

{\fonttbl {\f1 \fmodern Courier New;}}
{\stylesheet {\St \cs1 {\StB \f1 }{\StN tw4winExternal}}{\St \cs2 {\StB \f1 }{\StN tw4winInternal}}}

However, I'm not sure that this is where the problem at hand is to be found. Does anyone know how to fix it so I can import it into Trados?

I often find that Studio can't import TMX files generated by Wordfast. You can try alternative routes such as, for example, import your Wordfast TM into Wordfast Anywhere ( and export it as a TMX from there. There seems to be less likelihood of an imperfect TMX this way and Studio is very unforgiving of imperfect TMXs.

a solution which worked for me Mar 24, 2014

hi Theo, following on what John says, I would also encourage you to use Wordfast Anywhere.

I had some very, very old Worfast TMs with the language pair EN-EN > ES-ES. I managed to import them to Worfast Anywhere and export a .tmx.
then I created a new Studio TM with the language pair EN-US > ES-ES.

then I opened the .tmx produced with Wordfast Anywhere in Notepad++ (freeware) (you can also use Window's Notepad, but it's slower), and changed the EN-EN language code, to EN-US, so it would match that of my fresh Studio TM.

Saved, and imported to the Studio TM succesfully. most, not all, of the segments of the .tmx managed their way into the Studio TM without disturbing error messages.

hope it helps.
