Hello Radio Star, I think that the Greek Language pack is only available for version 3.8, and so you will have to upgrade your present package. This need to be confirmed. However, Wolfgang is on holliday until the 21 June. Can you wait until this time for a reply to your question?
Raduga 3.1 had not been translated to Greek. If you want to translate it, I can send you the required files. However, I strongly recommend you to use Raduga 3.8. And yes, I think I'm going to spend my next holidays in Greece.
Welcome from your holidays. Can come in Greece the other month in the Olympic GAMES they will be splendid! If us you make a good economic offer we agree to buy Raduga 3.8 RADIO STAR HELLAS (GREECE)
