ROTMG character infinite load screen in flash only

So whenever I go on flash player on my hacked client everything works fine I go to my character list click one to play and then it gives me this infinite loading screen with my character running now on the realm website I can play fine

but like I said on chrome I can still play so anyone know why this is? and how to fix it

1) Wrong forum section.

2) Make sure your client is up-to-date.
