FlashCrack

Hey Fellas, I was testing my modpack to figure how it works before I make the actual one, and basically I am unable to download, after getting my dropbox download link, it goes to 98% like three times before I get this message: Here is the link to the modpack: https://www.technicpack.net/modpack/flashs-test-modpack.1063915 And here is the modpack location url: https://www.dropbox.com/s/t98x4juoz08fhnn/modpack.zip?dl=1 I hope someone knows how to sort this out
