On a few scenarios on greenfoot.org there's an application error which says classNotFoundException, is there anything I have to do to make those scenarios work, as with the scenarios that incorporate UserInfo.
When they are downloadable they usually work offline but on line it has the error.
Look at this scenario for example (by these scenarios I usually see that they work for other people because they are talking about the scenario while all I see is a white frame with an error on the top left, and when I click on it, it says classNotFoundException).
Try clearing your Java applet cache. This has solved similar problems for me previously. I normally clear both the applet cache and the browser's own cache, just to be sure.

I (just) followed the directions that were there and I still get the error. (I followed the instructions exactly, meaning I only left the first 2/3 check boxes checked.)
The following is the exact message that I receive:
Application Error X
ClassNotFoundException
greenfoot.export.GreenfootScenarioViewer.class
<Details> <Ignore> <Reload>
I am also NOW on the latest version of Java (and Greenfoot).
When I click on the button that says "Details" a new window pops up which says:
Java Plug-in 11.121.2.13 x86
Using JRE version 1.8.0_121-b13 Java HotSpot(TM) Client VM
User home directory = C:\Users\yehuda.HOME // (I always said that Nosson1459 was two people)

c: clear console window
f: finalize objects on finalization queue
g: garbage collect
h: display this help message
l: dump classloader list
... I have no patience typing the rest and I couldn't copy-paste it so I'm stopping here.
