Export Error code 3 - Error compiling movie

I have been getting this error when trying to export media.  

I'm running versions 22 of premiere pro and media encoder.  

It was working a few days ago, but suddenly getting this error.  

I have tried uninstalling/reinstalling and rebooting.

I have also selected the render to software only.

My videos are basic, don't have any effects or cuts in them.

What is going on?
