I had same problem with all of my Apple accounts. My gmail account worked no problem.
Would you be able to put the same link on there instead of emailing? I'm guessing I'll be getting more spam in the future.
Regardless, great lower third.
In a related issue, I had problems downloading your Bullet Point Template. I discovered that your setup for that is a popup window. For security reasons I keep "Block Popup Windows" checked in the Security tab of Safari Prefs. I had to uncheck that, download, then turn the blocker back on.
Anyway, I do appreciate these excellent freebies - Thanks!
