Do you have wifi also ? If you do you have to change both adapters . This program may help Link Also delete the text file in the C:\AeriaGames\AVA\Binaries\XIGNCODE.USA it is named xingcode . Then use ccleaner and clean the registry .
When you have done that use tmac change the ethernet and wifi if you have a wifi adapter . Then run the hack from inside the rar do not extract the hack from the rar file . I hope this helps .
