You would have a better change for a response if you posted in Tech Support, rather than Game Bugs.
The Awesomium process is the app that runs the Trading Post. If it isn’t working, you can not access the TP. You may have some corrupted files, have you tried a -repair?
For an individualized, and assured response, contact Tech CS using the link at the top of the page.
Good luck.
Interesting. Gazillion a few months back got rid of their Awesomium based system in favor of something else and I believe it helped those complaining about it immensely.
They’re just a phone call away.
