If you want your software project be successful, you need to have many people understand and use it. That's why you need a professional translation.
And when I say professional, you know I don't mean something that looks like it is translated with Google automatic translator!
What you want is that the translated document is not only understandable, but that also uses the same style, tone, and the correct terminology of the original one.
Also if you are going to translate a software you need to work with people that knows the tools we use (did someone said .po .pot ?) and has experience about software localization.
