Since I have already posted this several times and seems to work. I've decided to make a post so people wont have keep making new threads.
You may be suffering from something some other people have suffering from. I dunno if yours is the same, but a possible solution is mentioned here:

Quick and dirty summary of the thread. You might be accidentally logging in twice. This is due to some weirdness in how the launcher responds to double clicks. The solution, select your character with one click(If not already selected) and then hit the connect button. It should work just fine.
