Error unzipping file

[xXSpearkill3RXx]

I've made a modpack called Techno Farm and it does about a 10th of installing then it says:

Error unzipping file for the following pack: Techno Farm

Error unzipping file C:Users******AppdataRoaming.Technictechno-farmcachetechno-farm-2.0

So i try to open the archive in the cache and, It says:

C:blah blah blah

Archive is either in unknown format or damaged.

Please help me!

And i cant get more modpacks or update them, it just says the same thing. I cant play tech farm or the aether! If you have a solution, please put it in text, not video.

Good sites for file hosting that have direct downloads are DropBox and... crap cant remember that other one. DO NOT USE WEBSITES WITH A CLICK-TO-DOWNLOAD. (mediafire WILL NOT work)

But theres one thing i dont understand.

My other 2 modpacks worked, and i just set it up on the website.

How ever they dont have mods with them, its just the minecraft.jar, and i deleted them.
