I am working with Premiere Pro CC and Encore CS6, finished one project, burned blue ray, all OK.
On the next day, i could not start a new project, encore opens, the error message comes, it is only possible to close encore.
Opening a old project causes the error: no access ??? Same problems with admin rights.
I have a Windows 8.1 x64 System, installed Encore CS6 again, the error messages come every time.
>Same problems with admin rights
Right click the program icon and select Run as Administrator, which is NOT the same thing as running the computer with the Administrator account, and which fixes several "odd" problems... To create a two layer DVD or a BluRay, you must have Encore set to use the Run as Administrator option

What is the specific error? Post a screenshot if complicated.
