what do u mean by that? do u mean the 1.6.4 servers no longer work?

kk thanks for your time ill do my best

OK,

I know that support isn#t offered for that old Version, but it looks like some mod on the server side needs another mod (Like NotEnoughItems needs the CodeChickenCore)

 

The first Exception mentions this "missing mod".

 

The second Exception means, that your client sends some data to the server, but the server doesn't know what to do with that data. Maybe the former mentioned missing mod would handle that data.

 

greetings

I still get the Java.lang.nullpointerexception error:/
