Volcano Man updates available for downloading

[Al]

I keep getting compressed file invalid or corrupted. I downloaded all of them to a file where I keep each title with it's own scenarios and updates, then extract from there to the actual title. When I went to extract to each title, I got that message. I then went to open instead of extract to possibly copy or cut and paste and got that message. I then went back to his site and tried to open the file there and got same message. Any ideas?

Mark,
Have you tried to download the update by clicking on the portrait rather than the "download" button? Seems strange but this does work for some...;)

That does help. Also, for some reason WinRAR seems to extract the files better than just plain WinZip.
