If you had taken a bit of time searching the forum you'd have seen at least 2 posts with the same image.
Anyways.
No one has answer this question as of yet.

But keep the conversation there, would probably be better than flooding the forum with this.

There's the translation!
According to the fella that so kindly translated the image, client version doesn't match the servers.
So at the moment I'm trying to run the launcher as Admin and hopefully the new version files will overwrite the old ones.
I'll post as soon as it finishes updating.
