New Language

A strange thing happened while I was working on my computer the other day.  Suddenly the language on my dashboard changed into a foreign language which was totally Greek to me.  I tried to re-set the language settings several times to English but nothing worked.  And little messages kept popping up while I was typing.  I suppose I should look on the positive side and be glad I'm learning a new language but then it's so confusing.  Think I had better "gorde" (save) this post before I forget and "argitaratu" (publish) it when it's ready.  Oh my God, what is "aurreikusi"? Help!
