Mods no longer load in new launcher version

When I try and run world edit, using forge in the new version of minecraft, there is an issue where Minecraft Forge runs, world edit does not load. I tried it with the old unsupported launcher, but it was less responsive, and doesn't use more than 2 gigabutes of RAM, and it worked on my old laptop which has an older version of minecraft installed. I made sure that I enabled Java Exe. And also, the forge, and world edit versions matched up. I have had no issue running Minecraft on any other version, but the new launcher version. I don't think it is unpacking it correctly.
