DVFilm often makes free updates available. To receive an update you simply request it by filling out an online form. Links to the appropriate form for your application can be found here. For Raylight products the form is here.
Some of the fields on the form are optional, the most important field you must provide is the email address used when purchasing the software. Without it, you will not be able to receive updates. To request a change for the email on record, there is a charge of $8. You can go here to request this registration change.
Once the request for an update is submitted, an automatic email will be generated and sent to the email on record. If you do not receive the email it is most likely because your spam filters have flagged the email as spam. Check your spam folders, or add the email sales @ dvfilm.com to your safe list and request another link.
