I got the same error last Sunday...thought it went away and it came back again this Sunday and have had it on Monday too...constant 90001/90002 errors on Balmung. Last time before these two occasions I had the problem around when the new expansion came out and the first week was hard to stay logged in.
I didn't really start having problems till I switched to Verizon Fios then I started having problems like this occasionally....and just on this game. O_O; Then I have also from time to time have lag problems during the evening...so I had to take on downloading WTFast. No other games give me problems besides XIV.
It sucks because I really want to enjoy this game. I'm hoping after work it goes away again like last week...its kinda wasting my money and I don't make much as it is. Q.Q
