Error unzipping:InvalidZipStructureException

Error unzipping:InvalidZipStructureException

Hi,

 I have a zip file (attached) that I’m trying to unzip using the CopyFilesTo function.  I get:

Xceed.Zip.InvalidZipStructureException = {“The information contained in the local header does not match the information of the central header.
Zip file: c:\site\enol\UserUpload\2152047\GSCBOR.zip”}

I can unzip this with other tools without error.  I was using Xceed.zip.dll version 2.3.5566.0, and tried a trial version, 4.1.9373.11490, but that version also threw the same exception.  Can anyone help?

 Thanks!
