Are you a Trados user? Have you had problems with it recently? Namely, does Word crash every time you try and use Trados to do a translation? This thread on proz will help you remove the Microsoft Update which is causing the problem. I feel very ambiguous towards translation portals such as proz, but one thing is for sure: the forums are full of intelligent people willing to help their colleagues in a crisis, which makes them an invaluable resource for translators.
