I have recently started a new FTB infinity world and decided I want Compact Machines in the pack. I downloaded it striaght from the website (The curse forge one) and added it to the pack using the "add mod" button. Now when I try to load a world or create a new one it kicks me back to the title screen. I have tried everything from restarting my computer to re installing the mod. I hope you can help.

java.lang.IllegalArgumentException: Failed to register dimension for id 2, One is already registered

Change the dimensionId in the CompactMachines config.

I have changed the ID to all sorts of numbers. I these are the ones I have:
DIM1
DIM-1
DIM2
DIM-7
DIM-19
DIM-34
DIM-37
DIM-38
DIM-42
DIM-100
DIM-112

Plus mystcraft dimensions 1 through 12. I've changed the CM dimension to all sorts of numbers and I still get the same error. I've even tried deleting DIM2. I'm saving my config every time I change it and I've made sure there are no other dimensions numbered the one I put. I still get the same error message each time
(java.lang.IllegalArgumentException: Failed to register dimension for id 2, One is already registered)

What can I set it to?
