There are always issues with translators. The most noticeable one is... Most don't work anymore (after Google changed it's API policy). And the working ones use an API key often stop working when too much people use them together.
So I took an old beautiful project HG Universal Translator by Frank Ramos, which seems to be abandoned (last version is not working and is 4 years old, even the version sold for 1 L$ on SL markedplace is announced as not working) and made necessary changes to make it work.
