Java2Runtime Error: Cannot be loaded

Nice to meet you, TechyV people!
When I connected to a server, a Java applet was downloaded. But this error interfered and the applet could not be run.
I tried refreshing the page a couple of times but got the same result.
Anybody have ideas about this one?
A lot of thanks for any suggestions!
