Error code: FFXI 3001

[Effilil]

I have also been having this problem, though I am being disconnected after using outpost warp from Port Windhurst, and GoV/FoV book, and most recently, Port Jueno Abssea warp to Xarcabard. I would like to note that this has only been occurring to me since the 3/26/2012 update. The problem has grown worse since the 4/2/2012 update, in that occasionally I will be disconnected from the lobby and when trying to get back in recieving the messege that I have no content ID (which is active until 4/5 and will auto-pay on that date)

I am currently trying the advice listed in these posts to remedy the issue....

after checking all hardware/software settings, making sure all exceptions are in place, I am still having the same issue, as well as error code 3100. I even (temporarily) took the drastic measure of shutting off my firewall, all to no avail.
Since this problem began occurring only after the last updates, I was wondering if it was possible that it could be a software problem of some sort.
