i have got exactly the same problem. Ive followed the instructions did exactly what i was told to do my modpack doesn't crash cause ive tested it. the link is an direct download. i can't figure it out. And the most weird thing is that when i go to my .technic folder and open my custom mod folder and look in to the cache folder my custom zip is downloaded there with everything in it it just needs to be extracted and installed thats it.... any fixes or things i did't noticed..?? :x
