when I install the 0.84 jar file into the mods file then play. The mod isn't even there. i can't craft anything and it's not in NEI. The only other mods I have is planes, SDK's, BC and of course IC2 1.7.1. Can someone please help I was planning on getting this for my 1.1 server. One other person said I need to make sure IC2 is loading before rocket science, what does that mean?
