Can't download HPL2 Suite

[Wapez]

Hello,
I recently bought a new computer with windows 8 on it. Since I want to keep working on my Amnesia projects, so I downloaded the HPL2 suite. When I try to extract it with winrar, it says like this on most of the files in one big box: (translated from Swedish)

! C:\Users\Wapez\Downloads\hpl_editor_suite.zip: CRC failed in editor\textures\editor_cubemap_default.dds. File is damaged.

I'd like some help to solve this as I have already re-downloaded it twice and tried extracting it to different locations, including desktop, Amnesia:TDD root folder, and a newly created folder. I also tried extracting them one after one, and that didn't work either. Suggestions?

Thanks.
