It is probably not installed/not installed correctly on the server (most likely).

you will not find any ores in chunks generated before mod is installed, this is not bug and cannot be fixed (actually can, but will take ages for large map to generate ores in already existing chunks)
Is there currently something available that can accomplish this (other than using MCEdit to delete chunks)? I remember seeing something about it but I forget where it was

Ah REALLY sorry a bout that i was tired when i wrote the thread

Well i just posted asking for support about this... then i did a forum search for the error but found nothing... but thank you!didnt work -
I don't know if its related but whenever i place a block near a sign or an IC^2 machine/painted cable the texture briefly flashes (possibly updates?). With the machines for me it has no real negative effect, other than simple annoyance. For the cables and signs however it causes the cables to return to being unpainted and it causes the signs to become blank. No idea if its an IC^2 problem or something else.

I set up a small IC^2 server for me and a few friends, but every so often when somebody places a block everyone on the server crashes with

It also seems to persist in one area for awhile then move elsewhere; any blocks placed in the area will most likely crash the game. The mods i have running are:Client:
AudioMod
Buildcraft v1.8.1.1
IndustrialCraft^2 v1.15
Minecraft Forge v1.1.1

Flan's MP Utils (Crashes occured before installing as well)I also used to have Flan's WWII Guns v3, Flan's Vehicles v4, Flan's Planes v16.1, Gary's TurboModelThingy v2.3.4, and PlayerAPI v1, as well as their respective server versions. All of those are, at this point, uninstalled.
If it matters I also upgraded the world using IndustrialUpgrade (Going from 1.7.3 with IC 8.55_02 to 1.8.1 with IC^2 1.15) and even though it says only SSP worlds are supported, i see no reason why it should cause an error such as this (however I know very little about Java). After discovering the problem I then ran Chunkster (to no avail)
I also have no idea which mod specifically is causing the problem (or, however unlikely it may be, the vanilla software), but I decided to post here anyway (a quick forum search turned up nothing).
Running Java JDK 1.7 64bit
Code tags not cooperatingEDIT: Appears to happen when a machine is in useNOPE -
I have the same issue! Whenever i place machines or sometimes blocks near the painted cables they reset. Haven't restarted server yet though
