I got adobe photoshop elements 13 and adobe premiere elements 13, but I have a MacBook pro and it doesn't have a disk drive so is there any way to download those using the serial number on the box?

You can also download the trial version of the software thru the page linked below and then use your current serial number to activate it.
Be sure to follow the steps outlined in the Note: Very Important Instructions section on the download pages at this site and have cookies enabled in your browser or else the download will not work properly.
