TDM Cars SVN wont work

So i am trying to install the TDM Cars SVN and i get this error

zlib (uncompress): corrupt data: Decompression of svndiff data failed

And it only downloads materials, do not upload this svn…

I am using this code: http://gmod-dl.googlecode.com/svn/trunk/TDMCarpack/

Try again. If you download TDM cars in a folder. Delete the folder and remake one and retry it in. (or else try to delete .svn where you did the download and retry)

i tried but always i get same error.

What you use for download the SVN ?
