Hey Vittorio -
Brian has been trying to make it so that languages can be installed after the fact, and that caused some major problems after installing SR6 RC1… SR6 RC2 is supposed to fix this, but looks like there may still be some problems. If you go into Control panel>Programs, do you see any language packs installed (there should be one for English, I think…) If that’s in there and you still don’t get English, you have a problem…
You might try redownloading the English language pack and installing that to see if it helps, you can find it here.
