are there any errors showing up when you press f2 and go to scripts?

my guess is that despite what youre doing with the server option weaponorder your movement is attempting to do things before every resource it relies on is initializing

if all else fails try re-adding the movement weapon on login like so:

player.removeweapon("-System/Movement");
player.addweapon("-System/Movement");
