I will get to it as I can; however, from what I heard in IRC, this was an "unforced" patch. In other words, you didn't need to patch the client to use Aion.
With Aion/isxAion, you should only run the patcher if the game will not work launching Aion as normal with InnerSpace.
But yea, it might be a couple days before I can get to it -- but I will as soon as possible (updating isxaion is not as fast/easy as updating the other extensions.)
