Make sure u have the most up to date Java (see this thread (click me) and Java can be updated from http://www.java.com/en/download/windows_automatic.jsp

Yet it could also be a Zone Alarm issue! See these following threads: Thread 1 , and thread 2 , and this thread, but especially this link!! (Woops, lost it for a moment.) Hope this helps. I'd suggest that if u update Java the problem may go away, so try that 1st. Good luck.
