If you can sha1sum the contents of the disc and they match then
obviously the burn went correctly.  You could also try burning
software that does its own checksum.. I'm afraid I can't suggest any
in windows.  sha1summing the ISO file itself will reassure you that
you have downloaded it correctly but if the content of the actual
disc is different (and you have verified this without using the CD
itself) then you must begin to suspect the burn or the drive.

I wouldn't proceed with the install at the moment as the error
suggests there definitely is something wrong with the discs or the
cd drive and I can't see how the install would be successful.

This is most likely due to PGP/MIME signatures being attached and
then your mail client not recognising that it can and should still
display the parts inline, leading to you having to click on them.
This is a well-known deficiency of Microsoft Outlook family,
although I am suprised that your webmail is also equally broken.

The answer is to use better software.  I've heard that Gmail handles
it fine, for example.

Cheers,
Andy
