EDIT: I know the title says "with just forge", but I finally got a modpack with just forge to work only to try and add other mods and have the same error pop up. I do not know how to change the title.
Okay, so, I've been trying to create a modpack for my own personal use, but I'm having a lot of trouble. I keep getting that "trouble unzipping file" error and I have tested all these mods together on my actual minecraft, so I know it's not because they conflict with each other.
Here is the link to the pack on technicpack: http://www.technicpack.net/modpack/yoyohaylis-modpack.590450
Now, I've searched through the forums for possible solutions and the same things seem to get repeated a lot, but I swear I'm doing everything being told to others.
1. I downloaded Minecraft Forge version 10.13.2.1291 for Minecraft version 1.7.10
2. I made 3 folders: mods, config, and bin
3. I put the forge file into the /bin folder and renamed it as modpack.jar, making sure there were no extra extensions on the end
4. I placed all the config files for all the mods in the config folder
5. I placed all my mods in the mods folder
6. I packaged those three folders into a file called "yoyohayli_modpack.zip"
7. I hosted that file on dropbox, making sure to follow the instructions on here: '?do=embed' frameborder='0' data-embedContent>>
If someone could take a look at what I have and tell me what I'm doing wrong, that would be great. I got a modpack to work with purely just forge, but as soon as I add mods, I get that error.
