Solved is this Right??

As the third photo shows, you need to downgrade the game. Unfortunately, we do not have a downgrade from 5.6 to 5.3. You will have to download the game via torrent again. If you want to keep both, you have to make a separate folder for Aion 5.6 and Aion 5.3.

 

If you still have your 5.0 files, just follow the guide here: http://forum.gameznetwork.com/threads/official-torrent-client-5-3-0-18.204831/
If you encounter any problems along the way, you can send me a private message. Take some screenshots of any error messages that pop up and send it as well. Have a nice day!

Closing.
