Now it Wont Load JmonkeyEngine At all It says Javx file not loaded or something?

Please, you must show the exact error. It is impossible to guess what it says, what java you have installed, how you start it, how you try to “open” projects.

Try reinstalling the SDK (make sure you use the latest SDK too).

i just got it today the error says

The package containing the class javax.swing.JComponentBeanInfo was not loaded.
