I downloaded the trial version of Premiere Elements 12 and decided to upgrade to the full version, so I purchased it, downloaded it and installed it. Put in the serial number I had been sent via hotmail etc. Eventually I was told to restart the computer which I did, and when the computer started up again a window was automatically opened up which showed a page from adobe's webpage, where it said I had to "log in and continue the download of the software purchased from Adobe Store". I clicked this link which took me to another page where I was told to select my country, then I was just taken to the "adobe.com/products/catalog" page. Now what? When I open the Premiere Elements 12 icon on my desktop it is still the trial version. Some help please?
