So i got my beta invite in battle.net, download client, had problems with patches but got it finished. Now i'm getting Unable to connect, http://img267.imageshack.us/i/97191883.png/. I tried the fix were you download the cache file but i couldn't find the Application Data folder in my hard drive. I also can't post on the official cataclysm beta forums, it won't let me choose a character.
