I can't create iso file or burn BD.
I got "file can not be created. Another file with that name exist" error after I updated it to newest "built". It went back to normal after returning to previous update. Be aware of it before you update. what is going on? a bug?

You might try moving all the project files from the current drive to another, and renaming the folder it is located in as well as all elements of the project.

Also, if you are using a DVDA project and altering it to make a new project, you should instead start with a completely new project from scratch, rather than replace media files for a new project.

thanks; I will try to do so; meanwhile I went back to previous version and the problem disappeared!
