I've found that the Nether is DIM-1, the End is DIM1, but from my research DIM-100 is a dimension called "Deep Dark", which is a part of the Extra Utilities Mod. When I've opened up my world save just now, all these files are now back on their own, and I hadn't entered the other dimensions yet at all, so I guess it doesn't matter any more. ah, thanks for the help you've provided, it's greatly appreciated.

I created a copy before I did anything, so it should be fine if I just put that in right? And is it just DIM-1, or DIM1 and DIM-100 as well that are fine being kept?

Thanks for that, deleted the 4 files (DIM1, DIM-1, DIM-100 and DimensionalDoors) and it worked perfectly. Luckily enough I didn't have anything in the dimensions.

Just a bit of extra info - This only happens in this world for some reason (which happens to be my main one), and I've tried replacing the world with a copy to try and do... something... but nothing changed.

I've seen posts with this happening tekkit on servers, however this is on a single player world I use. I have attempted re-installing the pack multiple times, and also on different versions of the tekkit launcher, and the same error comes up, with the game sometimes not even loading and closing itself down. There are also text files within the crash-reports folder of TekkitMain saying the following whenever the game crashes (the detailed report is a bit too long to post): ---- Minecraft Crash Report ---- // You're mean.
