Unzipping Error

[bradenhelmer]

Ok so i am trying to make a modpcak for my friends and I to play on and i have tested everything on barebonespack, client and server are working fine but when i upload my file to technic it always says error unzipping when i attempt to install it. The only time it ever downloads is when i zip the modpack.jar but then my mods are all gone. Im just wondering if there is a solution cause I've spent hours on this thing and i really want to complete it, Thanks.

Make sure it's really a zip file and not rar.
