Open Internet Explorer, click on Tools menu on the top bar, select Internet Options, Advanced tab, scroll down to "JIT compiler for virtual machine enabled". If it isn't ticked, click a tick in the box, click apply, OK, and then reboot your machine.
Another factor could be your Firewall, if you have one. I have Zone alarm pro, and in the Privacy setting, Mobile Code control, there are 2 boxes referring to Java. If you have Zone Alarm, ensure they are not ticked.
Maybe other Firewall programmes have similar settings. If you have a Firewall, check this.
