Il faut recommencer.
You may open trial projects when you buy the program, and you may also remove the watermark from exported video as long as you still have the project file
Remove Trial Watermark http://forums.adobe.com/thread/433730?tstart=30
You do not have to repeat a project file (.prel) created in the tryout. It can be used in the purchased program and without the Adobe watermark.
Let me explain the situation that exists for Premiere Elements.
You cannot get rid of the Adobe watermark from an export from the tryout project file, neither a file saved to the computer hard drive or a disc end product.
But, you can remove the Adobe watermark from the project file (.prel) from the tryout when that project file (.prel) is opened in the purchased program.
To do that...
Open the project file (prel) in the purchased program, go to Timeline Menu/and click on Delete Rendered Files. The Adobe watermark is gone. You can
edit your project which no longer has the Adobe watermark.
Some of us have found that using Timeline Menu/ and clicking on Delete Rendered Files is not necessary and the Adobe watermark disappears
just by opening the tryout project file (.prel) in the purchased product.
Determine which of those two ways works for you.
Again, you should be able to open and edit your tryout project file in the purchased program.
Thank you very much indeed John
