Cannot Log Into Game

System

I have pre-ordered, did beta, and assumed that the problems that I posted about would actually be taken care of, but have not. I still am having serious difficulties getting into the game. I get a mixture of messages such as "Server Busy, try again later" "Disconnected from Account Server" & "Login Attempt Failed" I have a better computer than either of my two friends playing this game, and the exact same connection, yet they can get in fine and also stay in the game without getting kicked out at all. I, on the other hand, have these issues keeping me from logging in for anywhere from a few minutes upwards to an entire day, as well as being kicked out about 75% of the time when I zone/load new areas. Combined, these problems make the game nigh unplayable.

Can anyone explain this or perhaps lend a hand some how? Head start is underway, and I am missing precious time...
