Unable to unzip Default obsidian sound files

[knx cobra]

when i download the V4 and some of the other fonts from the US site, i cant seem to open them saying that the folder is invalid
anyone else experienced this?

What program are you using to unzip them?  I know that sometimes, I have convert files and unzip them using another program.  I've never had this problem with US fonts, but it's happened with other files.

Tried  winzip, and 7zip i believe, on 2 different computers

If it's a .zip, you MIGHT be able to convert it to a .rar and open it with Winrar. 

I've used this service before and haven't had any problems:

*Note*  I am not super techno savvy.  I'm only saying what's worked for me!

no luck

comes up with this message

Your file conversion failed for the following reason:
Either this file is not a zipfile, or it constitutes one disk of a multi-part archive.

Convert another file

(i belive its the latter as this is what it tells me when i try open them)
