Unzipping issues

[Khamos]

Hi all just joined tonight.
I've downloaded all 10 sections and have tried extracting the main folder. When I do it says the same volume can not be used as both the source and the destination. After that an unexpected error pops up, if i skip it goes to all files so none of them en up extracting.
Im using windows 8 if that make a difference.
Any one have similar experience/solutions?
