What's wrong is that you're trying to violate their email privacy settings. The 5% of emails you did get are from the contacts who shared their email with you and enabled the "Allow connection to export emails" setting; the other 95% did not choose to let you export their email address, as is their right since it belongs to them.
Originally I was the one who put all the email addresses into linkedin to begin with (in fact back when I started using linkedin, you needed their valid address to link up with them). So it's my own contact info list, or was. Since I couldn't get the info back out, I ultimately deleted my linkedin account.
