Update: I am using IC2 v 1.97, or whatever the current is.
I am trying to install IC2 on my server. I went ahead and made a completely new minecraft_server.jar and world file. I got on and went mining, and I was able to mine up 
,

, and I was able to also craft an 
. But when I tried to craft other machines such as the 
, I was disconnected. Because other things are working (such as the ores) shows that the mod is installed. Please help. This mod looks awesome, but so far I am more than frustrated.
The Forge version I am using is the latest recommended build (3.3.8.152).
I have nothing else installed on the client or server. Forge is no longer dependent on Modloader (nor ModloaderMp), so I assumed I didn't need it. (I also tried with Modloader, and it still didn't work). The mod runs absolutely fine in singleplayer with or without Modloader.
I'm so sure what a crash log is, but this what was printed on my server (if there happens to be a spelling error, that is because my server has no desktop gui, just a terminal, so I can copy it electronically, I have to manually copy it):
