thanks again for following up.
Interesting to learn that Trados 2007/2011 is using the list posted at the Microsoft site (my guess is that both MSFT and Trados use the ISO standards for language-country pairs).

I'm not sure what happenned to that article so I'll need to follow up with the KB Manager tomorrow. But this was for SDLX anyway (a different product developed by SDL), and not Trados 2007 to 2011 as you actually asked for, so hopefully you already have what you needed?
