Hi!

I have translated a short extract (200) words from a document in Wordfast Pro 3 and created a TB. Now I want to go back and load and continue to translate the remaining 300 words, and hence extend the TM, and so far (3 hours!) haven't managed to do it.
Does anyone know how I can add about 20 source segments to an existing TM?

Thanks so much if anyone can help!
