It happens on a daily basis where I go into a limbo. Nothing moves everything lags. Is my client corrupted or do I just disconnect. May I also add when I reboot the game it still doesn't work. For example when I head into a level of some sort I have this black screen. Any help is appreciated.
It seems you experience lags, and these "Black screens" as you describe might mean your client is corrupted. This is probably a Graphics card glitch that popped up with the new GUI. I think you can solve it by reinstalling SK.
To make SK as fast as possible and prevent lags, close every possible background program. You can close several processes that are hidden by running the Task Manager. To open it right click the clock in the down right corner of the screen and select "Start Task Manager".
