I can confirm that ISboxer works in Aion at least as of August but I haven't tried after the expansion. I never got the command line method to work but you can use the launcher just put a 30 second delay between times it lauches the windows or just click on the team name multiple times from the isboxer icon in the system tray to start any missing instances.


As a note you have to use the launcher not the .exe or it won't work just make sure you turn off the check for udate option in the launcher.. Also you will need to set the client to launch in a window'ed mode.
