As you guys already know the RYl2 client.exe is not fully stable against server movements and file log movements,
so sometimes you'll get an error when it's really a bad situation, by example while upgrading,
and you might loose your eq because of that.
Here you see how you can prevent to loose your eq in an error.

If you got an error while upgrading or moving your eq, do
NOT use your mouse to logout and NOT klick away the error.
Simply use the computer reset button.
next time you login you will refind the eq in your mouse.
