Sorry for long response.
I've checked, you have no bans, so just don't worry about this. You may start from some standard options mentioned here fix the issue with loading:
delete modifications if you have any (you may also start game in a "Safe mode", check this with the right edge of "Play" button in WGCenter)
"check and repair" client via WGC >> Game Settings
delete your preferences.xml file in the game folder and set everything manually again with the next game launch
choose another graphic settings and check the result
You may start with any and check if it works for you. If it doesn't help you, please create WGCheck and send it to our Support in the ticket with some notes and screenshots.
Thanks everyone for answers and help.
