Well.. ok, here goes:
First off, I'm on Vista.
So I delete everything PS off my computer and try to download the new 5.0 client off one of the USA mirrors.
It downloads and I install it.
I go into the menu, click play, and I get one of those error messages. So.. I hit repair, and it starts downloading a bunch of stuff, most, if not all art updates. It ends up finishing in about 20 minutes, so I hit Ok and then hit "Play" again. It took me to the old 4.03 client and said the server was down, I X'd out, tried to get in, an error message pops up 100% of the time.
So I reinstalled, and the exact same process happened again.
Any help?
