You must keep your BROWSER clean in order for it to run at an optimum level.
To do this you must clean your cache on a regular basis.
If you find your game will NOT LOAD or it is slow and
sluggish, use the appropriate link below:
After Cleaning please restart your Browser.
If you are using Internet Explorer then I recommend you change to Google Chrome.
Internet Explorer (IE) is bug-ridden and a much slower browser. However, if you wish to keep it then I strongly recommend you upgrade to version 9.
After you clean your browser, if the game is still not working properly try doing a FULL SHUT DOWN of your computer,
Wait a few minutes; then restart.
This gives it chance to totally clear all the temporary memory so that it can work more efficiently.
