When I try and install using mod manager while having premium it says archive for the mod is broken. HELP

[ren1009878]

As the title says the mods i download just say that the archive is broken over and over again no matter what I do. it all happened when I got this collection on top of my other 400 mods by accident and when I got rid of the collection and tried to get my other mods back it just said that the archive was broken over and over so I reset my entire computer back to new and it still did it I've even made two other accounts to see if that was the problem and nothing and its even worse when i have premium because without it at least some of them get by but with it nope. I'm willing to do anything to fix this so please help.
