Problem reading large files - Header checksum is invalid

Hi all,

I am trying to work with large files and while trying to extract information, I get the following:

Source: ICSharpCode.SharpZipLib.Tar.TarInputStream

               Method: ICSharpCode.SharpZipLib.Tar.TarEntry GetNextEntry()

               Message: Header checksum is invalid

               Additional info: Error occurred importing feed file. Message:ICSharpCode.SharpZipLib.Tar.TarException: Header checksum is invalid

   at ICSharpCode.SharpZipLib.Tar.TarInputStream.GetNextEntry()

Looking forward to hearing back.
