I made a short movie with the trial version Premiere Elements 15. All the movie includes the trial mention in the middle of the pictures, it's ok.
But I bought the software, I put the serial number... and the trial mention is still here !
What have I to do for remove it ?
Have I to make again the movie ?
Thanks for your ideas and suggestions !
Delete the media cache files, save your project and back it up, restart the computer, and export your project again. You can't remove it from a movie that has already been exported.
Thank you for your answer; now it's fine.
Sorry for the delay... for my answer !
