Yes, I have about the same problem.
When I was starting the downloader and it downloaded the new downloader.. the mess began.
Already in the downloader I had a complete Chaos of the Skin and the text, which overlaps itself over and over again, because the old text wont be deleted or moved after other text is set.
Well, I hoped it would be different once I start the game, but in the setting-tool, as well as in the game itself I have the same problem.
I start to feel cursed or something, since every time I want to try this game I have to learn for Exams, the server is down, or something like this happens

Well, guess Ill have to live with the excitement if PS can make things better, where WoW messed up from the view of a RPer, and maybe Ill just try to reload the client... ^^
Of course every hint that would prevent me from downloading the 200mb over again are welcome.

Ok, un- and reinstalling wont do the trick, the downloader still is a chaos of frame and text, just when I update it.
