You may hate me for saying this, but part of your problem is that you are using an Acer. They are incredibly low quality computers, I should know. I've had my Acer Aspire since June 2008 and I used to be able to play WoW on it without too many issues. Now, I can barely even play FH on it at times, with many lag issues, even after dumbing down all of my settings.
Figured I'd give you a forewarning on that one.
Otherwise, I honestly think many people are still experiencing problems with the Server and that will likely keep happening until Raz has had a chance to talk with the Server folks and get things settled. Unless my eyes deceived me, I believe he mentioned having hacked FH through their servers, so the game is probably not running at Optimum Capacity.
Partially just a guess on my part for that last bit, don't bite my head off if it's wrong xD
