Corrupt Files Downloaded

Hey guys,

I’ve downloaded a few class files and have received the following message.

" File is corrupt"

[Unknown Compound Stream Type]

This is after using winzip and 7zip.

Any help would be appreciated.

Sorry figured it out, had to open them inside live.

Next question is, once i open the file it says my computer isnt authorized, so it will not save anything?

Ive authorized my software already

Is it ableton thats saying its not authorized?
