Psychoseen

I know the server isn't down because over 900 other people are playing. I can log in to servers but can't actually do anything. I see other peoples messages for a second then it freezes me out. I can't move to new areas, battle, type in chat, etc... Not sure what is happening :/ Edit: I can't figure out how to delete the post but finally after 2 or 3 hours it lets me play again.
