New to Edbuntu

[Steve Hallman]

My name is Steve Hallman and I live in Augusta, Georgia.  I am a long time
user of Windows.  For the last year I have been really interested in Edbuntu
as I have three grandchildren, the oldest is seven and their mother is am
elementary school teacher.  I showed their mother Edbuntu and she was very
excited and totally unaware that it was free.  I ordered the CD and
installed it as a standalone workstation on one of my home computers.  I
downloaded the classroom server add-on cd and burned a disk and followed the
instructions and I continue to get an error saying the add-on cd may be
corrupt.  Could you send me the link to the correct add-on iso as that may
be my problem.

Thanks
Steve Hallman
