Moved to the Premiere Elements forum.
Photoshop Elements 12 and Premiere Elements 12 are standalone products. Typically after you download one, you designate the next and do that download.
Since you have purchased serial numbers for each of the products and you have been able to obtain only 1/2 your purchase, best contact Adobe via its Adobe Chat to correct the situation.
Click on the above link and, when it opens, click on "I still need help" to get Adobe Chat pop up.
I think that the "Downloading, installing, and setting up" category looks like a good choice. There is also another category that might be useful named "Orders, Refunds, Exchanges". But start with "Downloading, installing, and setting up" and let us see what that Adobe Chat group has to contribute and if it can correct the matter.
Please let us know the outcome.
As you have the serial number and are getting problems with the direct download from your purchase details just download the trial from http://www.adobe.com/cfusion/tdrc/index.cfm?product=premiere_elements&loc=us. It is identical. Just enter your serial number when prompted.
