Ars Magica and MCore

[Ever Runes]

I tried adding Ars Magica version 5.37.007, and MCore version 3.3.07 to the FTB Ultimate v1.1.2 modpack. I did this using the "edit modpack" option on the FTB launcher, adding MCore because I was told it was necessary for adding Ars Magica to FTB. However, it didn't work, game did not load, and I don't know what the error was.

this is the error report thing from FTB launcher. Can anyone help me with installing this mod? If it's ID conflicts, can someone tell me how to change IDs? I've tried before using mIDasGold version 0.2.5 (was recommended this) but the thing doesn't display most of the item IDs, and likes to crash.
Any help would be greatly appreciated.

Apologies if this is in the wrong place. I'm totally new to forums.

Try placing the MCore into your core mods folder if it is not already. If it is then the error is a known error 'mc = class net.minecraft.client.Minecraft', here is the link to the knowledge base article about it.

Moved MCore into core mods folder, launched the modpack. My computer blue-screen D:

EDIT: Tried again, got a "failed to start game" error. http://pastebin.com/X9Wc250K

Caught exception from Forestry java.lang.IllegalArgumentException: Slot 249 is already occupied by ic2.core.block.BlockTex@abcead when adding forestry.core.gadgets.BlockResource@1826b48

This is an ItemID conflict. Find the item in the Ars Magica config that has an ItemID of 249 and change it to something else. I suggest changing them to ItemIDs 450 to 470 when adding ArsMagica for all the conflicts. I dumped the ItemIDs from a fresh copy of Ultimate and those IDs were free.
