GRUB loading.. Welcome to GRUB! error: incompatible license Entering rescue mode..

[David Christensen <dpchrist.holgerdanske.com@gmail.com>]

debian:

I did a fresh install of Debian using debian-7.6.0-i386-netinst.iso 
today.  When I rebooted, I saw:

    GRUB loading..
    Welcome to GRUB!

    error: incompatible license
    Entering rescue mode..
    grub rescue>

I figured that there was something incompatible between the older ISO 
and current files.


So, I downloaded debian-7.8.0-i386-xfce-CD-1.iso and installed that.  
When I rebooted, I saw:

    GRUB loading..
    Welcome to GRUB!

    error: incompatible license
    Entering rescue mode..
    grub rescue>


Any suggestions?


TIA,

David
