'Try reinstalling' may be the most standard "solution" or tip I have ever read on SE (which may be a solution if there is evidence that this really fixes something). Also, "verify game cache" and "check files", what do you mean by that? Check which files, for what? You should update your answer with some more details.

This error appeared in my game too, but I tried it just more often (at different times). Out of 5 tries it worked once and I applied for a guild. It seems to be kinda buggy or sth like that; try again!

Thanks for accepting my answer. What a great game series! Loved the first especially. Enjoy :)

Other question: why don't you try to restore the password? What's the problem with that?

Resources + the achievement?

Thank you. In fact I finally noticed it myself (I have already freed all POW). I guess I had been playing always at the wrong time lol!

I laughed about this one. Sry for late reply

Is that question title appropriate? Doesn't it have to be a "clear" an "real" question? (this sounds serious, but rules are rules right?) :) [I btw laughed reading the question title :D]
