*Default list of Magic Farm 2 mods

ArcaneScrolls v2.4.5.21
DukeCore v2.4.0.12
BetterStorage_0.7.3.38
ArchimedesShips-1.6.x-1.4.5
CustomMobSpawner 3.0.0
DimensionalDoors-2.2.1RC1-306
DrZharks MoCreatures Mod v6.1.0
DynamicTanks2_v0.0.6
EmasherResource-1.2.2.0
EngineersToolbox-1.1.7.1
EnhancedPortals_3.0.0_Beta-3b
ExtraTiC-1.6.4-0.7.5
KeithyUtils-1.6.4-1.2.24
Metallurgy-1.6.4-3.3.2.18
UtilityMobs-1.6.2-2.1
Witchery_0-3-1_164

It can be seen that most of the additional mods are from Horizons. I have been running Mo'C (+CMS+the GUI cmod) without issue. I was originally going to only add Dimensional Doors, but decided it would be a good time to update the server. If I recall correctly, there were a few conflicts between mods the last time I updated the pack, most of which were fixable by reassigning some IDs, others I believe I ended up disabling the mods. Either way, I do not recognize the error I am coming across now and can't seem to quick-google an answer.

I would have run a clean-MF2 pack on the server, but I didn't want to risk losing items from disabled/non-present mods like Metallurgy, Mo'C, etc. Any help would be greatly appreciated, I've got a few friends counting on me to get our world back online and working.

make a new server and place all the new mods into it to see if it works, if it does place the world in the server and go into the server.properties file and place the worlds name in place of the name aside "level-name". if you are using MCProhosting then get filezilla and replace all the folders and text files in there with the server you have if it works

Just to clarify/make sure I do this right..
I'm renting space from Cubedhost/Multicraft. The world we're running is named "MF2World" (and the folder with all the world data is named as such). You're suggesting that I backup the folder "MF2World", then let the server generate a new world (with any old name, doesn't matter), to see if the server will boot up properly, and if it does, restore the MF2World and change the name back to MF2World in the properties file? Hope I got that right.
