We would like to help you but you do not present the information to help us to help you.
Please consider posting the following information
1. What computer operating system is your Premiere Elements 11 running on?
2. What error code are you getting and what are you doing with the program when you get that message?
"Licensing or something" is not going to do for a description.
Has the program worked for you and suddenly will not? Or, are you just starting to use the program?
We just had a success story dealing with a Premiere Elements licensing issue within the past 24 hours.
The solution might work for you also. But we need to know at least the above information before we can
marching into a licensing issue.
We will be watching for your follow up.
