While rare there have been issues with some customers getting the trial download emails. Assuming they have not been filtered out of your emails by the spam filters our customer support can manually send you a trial at any time. They can be reached at 1-800-325-2747. This number is listed right at the top of the contact us page as well.
If you send me your name and email address via private message (please don't post as a part of a reply as this is a public forum) I can also set up an email to be sent to you with our customer support department. To send the private message hit the small envelope icon underneath the search button in the forum page.
