Hello sk8boardd,

Thank you for your interest in Acronis Disk Management Software.

Please note that you should first register your product at http://www.acronis.com/homecomputing/my/products/registration/ . After the registration you will be able to download it at any time from your Account management (http://www.acronis.com/homecomputing/my/products/). There is no option to enter your serial number into the trial version since it differs significantly from the full version and you should download full version first.

We are always at your service should you have any further questions.

Thank you.
