Ok I tried a few things yesterday:
*file checked POL (no problems detected)
*file checked FFXI (no problems detected)
*Went in to my program files and moved some files out on to my desktop and repeated file checks (no problems detected)
*Moved files back to their starter location. (no problems detected after more file checks)
*Uninstalled Wings of the Goddess expansion and performed a file check (Yay it found something missing and started to download and update)
*After 2hrs + the update was completed so I logged in to mules and they worked fine but still crashed when I tried logging in to my main.
*I tried FFXI official windowed mode and full screen mode with no luck because it brings the same result.
*Someone in ls suggested I try logging in from a different pc so I spent 2hrs updating my laptop and it worked but I'd rather play on my gaming pc then my old laptop.
Incidentally my laptop was originally windows 7 but later updated it to 10.
The pc I am using is also windows 10.

Anyways...
*I fully uninstalled FFXI from my pc and installed It back then waited 9hrs for the updates to complete.
Guess what? No change, still won't connect once I try play my main character and my alt.
This game really tests your will to play it. It should be so much more easier then this!
