Hello if you were banned and can not play AVA enmasee version.
Use Iobit powerful uninstall ( google it ) to completely remove the game from your computer.
You may also have to change your hwid just google that.
Also use ccleaner and delete prefetch.
EDIT: It's not router i changed hwid and it works.
