Ok so first of all my computer hates curse and that's why i'm doing this.
I downloaded the Sky Factory 2.5 modpack zip from curse and uploaded it directly to dropbox without changing anything inside the file. However when I launch the modpack through the technic launcher, it just launches vanilla Minecraft.
