So yesterday I ended up disconnecting from FFXI, so I completely disconnected my internet to kick me out of the game quicker. When I went to log back in, I was having some weird issue.
I can make it through POL fine, then I get to the first screen that says "Play" up at the top (Where you have to sit and wait during maintenance), then when I click "Play" on the next screen, a gray window pops up that says that Windows needs to install FFXI. If you cancel it out, it goes to the next screen, then it pops up again, and again, and again, and again no matter how many times you cancel it out.
I went through POL and did a check FFXI files, and it said it needed to repair 1 file that was some sort of boot file. I did the repair last night (Took over 8 hours), and when I tried to log in this morning I was getting the same Windows is Configuring FFXI message.
Halp? ;_;
