The latest Java update is special.
By default it blocks now any applet, until you change some settings in your system control panel.



To enable applets like JavaCPC Applet, please change these settings:

Open the Java Control panel.

Jump to "Security" settings.

Change the slider from "High" to "Medium".



Now click "Edit Site List".



Here click "Add" and enter "http://cpc.devilmarkus.de" (Without the quotes)
Then just click "Ok" in all dialogues.

That's it!

Enjoy my CPC games ;)
