Edit: I am going through my worlds one by one, and there appear to be several that will not open. I believe there may be a common thread between them that is crashing the game. These are all vanilla saves, and some open and some don't.
-----
I have a vanilla world save that I am trying to load in Forge. However, the particular world I want keeps crashing. I thought it might be problem with the fact that I created it before I downloaded forge and my mods, so I tried opening the very first world I ever created. The weird thing is that world opened just fine, which means the mods don't seem to be to blame.
The error code's file name is "crash-2015-07-17_23.27.28-server.txt", which, unlike my other crash reports, does not seem to have anything to do with my client.
I think it may be a problem with the save as when I saved one of the structures from the save as a schematic, and then put it into a new world, the new world would crash too.
Here's the error report itself:
