Is there any way to fix it? I'm pissed off because I cannot play. I've been hosting a tekkit server for months,and I've never experienced alot of lag. I could open IC2 and EE2 stuff,but now I can't! I'm desperate! :(

Lag is out of question,I've got a good quad core processor and a 250MB/s connection speed internet. I cannot open anything even if it's lag-free. I can open vanilla stuff like chests and workbenches. I'm getting desperate! Please,anyone,help me! Edit:The server is hosted by me,so that makes it even more lag-free.

Title: Cannot open IC2 and EE2 stuff when I right-click it. Version: 3.1.1 OS: Windows 7 Home Edition x64 Java Version: Java 7 Description of Problem: Whenever I rightclick something,like a macerator or an energy condenser,nothing happens! It's like I didn't do anything. Please help me. I CAN open things in single player,but not in MP. Error Messages: Nothing happens. Error Log: No error logs!
