I recommend that you create a support ticket — that’s the only way to get direct help from ANet. There are a couple of troubleshooting tips in the technical support forum that you might be able to use: clearing out your internet/game cache, making sure your anti-malware software isn’t blocking awesomium.exe, making sure you are running the game with the proper credentials (windows), etc.
Good luck.
