I have received by email a pop quiz in the form of an excel document.
However, when I try to open it I get the message:

"File Error: Data may have been lost"

This causes the quiz to open but without the necessary pictures. I have
found the website where the file was originally obtained from
(www.quiz-zone.co.uk) and I have downloaded it myself but the same error
message occurs.

Everyone else that the email has been sent to have been able to open the
document without any problems.

Any help as to why this is occurring would be appreciated.
