Hi Graham
Make sure you do not have any download accelerators active before you download the files. (This can sometimes cause problems)

Have tried the files on native Xp,Vista and Windows 7 unzip settings with no problems, have also tried WinZip and WinRAR, with again no problems.
Hope this helps

Bill
