Is there a way to rollback Aion Versions?

It seems that my Windows update had done something to Aion and I went to the NCSoft Launcher to Repair (as you do) and I found that I updated to 2.0, is there a way to rollback to 1.9? Because I can load Aion to the Login screen and then it hangs.. Nothing seems to be working from that stage onwards.

I checked DirectX, I reinstalled from 0 -> 2.0, I permitted Gamez through my Firewall, yet I'm stuck but I'm assuming it's because of the 2.0 update.

Suggestions? inched:

Hmm, I'll see if that works, but the tutorial states that even with the 2.0 update you can still access the game, yet I cannot. I'll check anyways!

 

I could connect when I had 2.0 awhile ago, it was glitchy as hell. I just made a seperate folder for gamez (1.9) and kept the retail one 2.0.
