My Java thing wont let me login to the game server because of some sort of error: ClassNotFoundException, then it comes up with all this rubbish:

Java Plug-in 10.17.2.02
Using JRE version 1.7.0_17-b02 Java HotSpot(TM) Client VM
User home directory = C:\Users\MUMTAZ
----------------------------------------------------
c: clear console window
f: finalize objects on finalization queue
g: garbage collect
h: display this help message
l: dump classloader list
m: print memory usage
o: trigger logging
q: hide console
r: reload policy configuration
s: dump system and deployment properties
t: dump thread list
v: dump thread stack
x: clear classloader cache
0-5: set trace level to <n>

Best bet is to not go on adult sites, then these problems don't occur

lool no, my dad put norton safety for kids, so it wont let me

I don't mean to sound condescending or patronizing, I hate saying this all the time. Makes me feel like a jerk

Have you uninstalled then reinstalled your Java? 80% of the time this fixes most things.

You jerk!

Course he thought of this

You dayumm right i did!, it didnt work, so i did a selection of things the_saint told me, and i fixed it.

Glad to hear!

Here how to fix this if anyone has the same prob:
Download ccleaner from here

Uninstall Java using the windows uninstall in control panel.

run ccleaner and click on registry

scan for issues then fix all issues but dont back up registry

do this at least 3 times untill no issues are found..

Then reinstall java 6 or 7.
After all this restart your computer :) (courtesy of the_saint)
