I have recently tried to make a custom modpack. At first, it didn't download from Dropbox properly, and I had absolutely no idea what was wrong. The next day i tried to show one of my friends the problem... and it worked. I don't know why, but I'm not complaining, but now I have a different problem my pack opens in vanilla. When I checked the .technic file, all the mods, coremods, and everything else had downloaded properly. On a closer examination, it seemed that the modpack.jar did not go into the minecraft.jar properly. There it was, sitting 2 cemtimetres away from success, and I could have moved it manually, but I wanted everyone who downloaded this pack to be able to have it plug and play, and no one else seems to have this issue, so why do I? I'm probably making some silly mistake somewhere along the line, and if anyone knows what I have done incorrectly, it would be much appreciated.
Here is a picture of my bin folder:
