Error(s) with Redpower2 Control Blocks

[Maliam]

Hello, I was hoping to avoid asking for help on this, but everything i have tried has failed and i am out of ideas.

Any redpower2 control block, doesn't exist on my server. Yes i made sure that they are assigned to the same I.D. clientside and serverside. I was hoping when i upgraded to 3.1.1 it would have a fix, but also no. I've tried to re-install anything from redpower2 itself to the entire tekkit both clientside and serverside.

I've been searching for people who have a similar issue, but i haven't found any.

Whenever anyone on my server tries to craft a redpower2 control block - they are instantly disconnected by an "Internal server error"

The console gives the following on any attempt to use/craft/hold any of the items:
