When you ask a question you need to provide some basic information
Starting with exactly which program are you using?
-Photoshop Elements or Premiere Elements?
Mac or Windows, and EXACTLY which version of the operating system?
Recent Mac AND Windows operating systems have been known to cause "odd" problems
Are you using a computer Administrator account with full read/write permission?
i thank you for taking the time to answer.
my software has been installed by the reseller of the computer.
i am on Windows 8.1 64bits
32GB ram and NVIDIA quadro 4000 built for softimage3d and maya (some very "high speed power" computer)
I am administrator.
its adobe premiere elements 13 that has been bought and installed
by the reseller at the moment of handing me the computer.
i suspect he has installed an evaluation version by negligence.
but i might be wrong
its only now, one year after , that i have to use the software to edit my animations.
do you know what is happening?
