This is on a Windows 8.1 PC.
The edit exported fine until I made one big mistake.
I created a Nested Edit to make a quick alteration.
Since then the following is now the case and I cannot go back to an earlier edit to fix this.
Premiere and Media Encoder will will no longer export my edit to any file format. Using either the Export Option or Media Encoder. Get a dialog that says "Unknown Error Compiling Movie"
There is nothing wrong with my footage. This edit worked fine and I export through Media Encoder many times until I made a Nested Edit within the Premiere Project.
I have tried all sorts of searches on the net for a fix to this but nothing seems to be current or indeed works.
Any help would be appreciated as this is a show stopper.
