An inscription "Made with the help of Adobe Premiere Elements" appears when editing a film across the screen, and I can't take it away, even after the export. Help!!!
Welcome to the forum.
That is the watermark embedded when using the trial version of PrE.
This FAQ Entry explains how to remove the watermark from a Project, after one purchases the program, and inserts their S/N: http://forums.adobe.com/message/1966673#1966673
Note: that watermark cannot be removed from an output file, if done with the trial, but only subsequent Exports.
