Details of the issue:

So it launches, goes through the load screen and right when the title screen should pop up, it closes and goes back to the launcher.

My old install was messed up so I did a clean install of the modpack. And I dropped my world files in the clean install (in the "saves" folder). And now it won't launch...​

Did it launch correctly before you put your old save in?

Anyway, take a backup of your world, click "force update" in launcher options and try launching again.

First of all, thank you! Thank you for replying. I see you in the tech support area a lot, and I think it's super cool that you try to help us out like you do. It means a lot to me, even if I'm not able to get my world back. It's still cool that you are trying to help out.

And yes, it worked fine until I put my old world into the "saves" folder. Let me ask anyway, when moving saves around, it is as simple as right clicking on my save folder (mine is called "Single-Player") and copying it to a different folder, and then clean install the modpack and then copy it back to the saves folder? Is that all there is to it?
