I have been trying to download Tekkit classic from the launcher, everytime it freezes on any random mod, I restart it and it gets past that mod. But it gets through alot of mods downloading and then it get stuck on Matmos, and will not download at all, no matter what I try... I have used it before but about a year ago, I even had a server running on it that was quite popular... Please help.

I Just tried downloading a community mad modpack to see if it was just the official ones were just broken. I got an error saying
"Error unzipping a file for the modpack,
Error in opening a zip file,
Please consult the modpack author."
