I've just made my own modpack a few minutes ago. Of course this being my first time making a modpack I have ran into issues trying to have it run.
Link to my modpack: http://www.technicpack.net/modpack/details/singhpack.439444
Link used for the Platform URL: https://dl.dropboxusercontent.com/s/2t8g1lgy62hd11u/modpack.zip?dl=1
The issue that I am running into is when trying to launch my modpack. It states the following:
"Error unzipping a file for the following pack: SinghPackTM
error in opening zip file
Please consult the modpack author."
Help is greatly needed.
