Referencing 100kbs...The simple way is to right click your Game Screen go to settings and in the pop up move the slider to 100kbs. It should default to that anyway unless it was changed previously.
What you do want to do after a game update is go to the game screen right click it, go to Global Settings and in the pop up use the Delete Data button to clear your Flash Cache.
After clearing your cache you will need to redo your game menu settings.
If you are having problems with Exp 8 you might want to try a newer Browser. I wouldn't suggest Chrome though. If your not have problems with game play then leave it alone.
