Its not my fault you are too lazy to adapt things.
1st- Using Interlude is just both ridiculous and dumb.
2nd- Obviously with all these wannabe Developers making their packs Packet classes get heavely changed hence, the patch won't work.
3rd- If you have eyes and a little bit of intelligence (no it doesn't require java knowledge) you can copy + paste the source with your own hands.
4th- Last but not least, don't be rude, I'm helping you for free and trust me, I don't mind not doing it. So have a little consideration if you don't mind.
Just get the protection again and spend 5 minutes of your time adapting it to your wananbe-pack. You'll see that in 5mins you'll be able to adapt it.
