Give it a few minutes just in case the download email is delayed. Check your inbox in a little bit. If you still don't have it try sending it again.
Additionally you can request another copy of the file emailed to you by clicking the appropriate option:
Once selected, choose a download format or send it to your email once more.
If you have blocked a prior email it is possible that there is a spam hold on us sending you emails. If for some reason this still doesn't work send an email to firstname.lastname@example.org and we'll help get it sorted for you!
