I managed to get into the game yesterday morning (really early in the day) and played fine for a couple of hours. I had just levelled my conjurer to level 15 -- giving me the ability to use my level 30 gladiator to finish the Paladin job quest. I was extremely excited to go back to Ul'dah from Gridania to turn this in. I decided to have my armour mending, first, before going back. As I was merrily running along; I fell through one of the bridges in old Gridania. It startled me, because I wondered if I would be trapped in the water and rock below it. I managed to find a well placed set of rocks that were stacked up like stairs to get back onto land and continued on my way about 5 or 6 steps until my game froze and then gave me the 9000 error. I was able to log back in....7 hours later. But hey, I'm a paladin now.......yay.
