Help with a crash report

[Salkras]

Basically, i had to remove redpower from my Modpack due to copyright. But now all my players get this issue:

Assuming you're trying to use the same world, all RedPower items could potentially cause crashes. That includes what appears to be your problem here, microblocks. I'd suggset either starting a new world or using a large-scale world editor to remove all RP items.

It's ok, i forgot to remove the NEI RP Plugin, and after removing it everything works fine. Thanks for the help anyway :D
