download of 1.9.1

Hi there,

I downloaded version 1.9.1 WinZip file, 9.367 bytes ( so I can update my R 
and use the vcd package) but cannot get the download from your Web site to 
unzip and install.  So silly!

The error message is :" Error reading header after processing 0 
entries."  I tried downloading from 3 different URLs, all yielding the same 
message when I try to unzip and install the file.

Could you please let me know what the problem is, including operator error 
on my end.  Thank you
