Server crashes right after someone joins (mod bug?) - The same happens in singleplayer.

[Axart]

Hi,
so, I've been playing my own mod-pack for a while now. It was all fine until yesterday, when my server started to have some problems. After searching through the crashlog, I figured out it HAS to do something with a mod which I've installed recently.
I'm suspicious of the "OpenComputers" mod and "Bibliocraft" mod. Whatever the problem may be, I don't want to lose my world and start again. That's why I created this topic.

What I did:
I deleted the OpenComputers mod and joined the world. I quickly realized that something is wrong (see picture #1). I assume that all of the block IDs have shifted because I've deleted the mod. Anyway, as I was looking at the crashlog, I found some coords (refering to the block that causes the crash), so I teleported to those coordinates, but all I found was the place where I placed a clock (from Bibliocraft) a few hours before the problems started.

I attached the crashlog. I'll be thankful for every piece of advice.
Thanks

Applied Energistics is crashing. Try to update it or contact the mod authors for more support.

Replacing Applied Energistics (alpha) for an older, stable release didn't solve the immediate crash.
I'm particularly confused by this part of the crashlog:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-- Block entity being ticked --
Details:
    Name: oc:case // li.cil.oc.common.tileentity.Case

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

"tile.oc.case1" would be a computer case from OpenComputers, I suppose. Those coordinates refer to the location of the clock I placed (as I mentioned).

Yea, I recommend you open the world in MCEdit and remove that block.

Did that, but the game crashed again.

I would make a backup of your server. Then on the copy of it clear your inventory with MCEdit. Let me know if that works.
