Anyone have any idea what is wrong?

Thanks,

Is your plugin's archive already opened by another program?

 

What do you mean? Oh the folder MinePay doesn't even generate.

 

I mean your .jar, if it's opened or accessed by another program it's possible that Craftbukkit can't use it.

 

I opened it earlier with The Unarchiver to check that the config was in there.

mb01 would that be the cause?

Anyone know?

Looks like your yankconfiguration is returning null make sure it's actually loading properly

 

How do i make it load properly? i have tried multiple times

 

I've explained the issue to him in a PM, but for future visitors:
