[Jhales825]

I came back to my server after about 1 month of going on it (no-one had gone on it since) and i saw that my ME-Interface and hard drives and all applied energistics blocks had gone (as well as some others) These are the most vital ones and i want to know the reason for this or if i can get them back. I am on Version 1.6.4 on my server and my client, and i tried all versions (1.2.9f 1.2.10cx and so on) and it dosent fix it, have i missed a vital one? Or is something wrong with my server? I DONT KNOW!!!!!!!!!! :''''(

If all your modded blocks are gone, check to see that the right .jar file is being launched when you start your server, maybe you are launching vanilla.
