If you’re getting the error(5): null thing. Also, hats!
I’m having trouble tracking it down, so I need your help. Please check your java console for any exceptions (large chunks of confusing looking code with line numbers) and email them to me at [email protected]
The java console can be found in Tools -> Java Console in FireFox and similar locations in other browsers.
In other news, want to know how people are doing the glasses and hats? Check out this nice tutorial by PuyoDead: http://www.minecraftforum.net/viewtopic.php?id=3413
