Yuditio Fragment of Memory 2/3 Problem - Froze Cannot log in

Ok so a buddy and myself was playing Aion, and we were in Reshanta. After talking to the NPC's to learn about the abyss and how to take control in abyss, we left to talk to Yuditio to accept/finish the Frament of Memory 2 (or 3...don't know which one.) and when we click on him and accept the quest, the game just FROZE and stayed frozen for about 10mins. I finally minimized the game and found there was an error on my desktop, saying something about an error occurring with the client. I reopened it and tried to relog...I can type in my name and password, but after that when I click on start, NOTHING HAPPENS! I can't even log in, it then says connection to server not authenticated, or something like that. Not only did it happen to me but it happened to my buddy and we live like 5000 miles away. Now we both cannot log in or connect, although my second computer which my brother is playing on, he can connect with his login and not mines. Someone please help me!!!
