Can't render at all, error dialogue.

Whenever I try to render my project I get the error dialogue:
"An error occurred while creating the media file .
Exception thrown by method called "

I'm not sure why this is happening and I have spent ages looking on different forums and websites for help and have tried updating, reinstalling, and clearing the cache. Also, the texts under 'Titles & Text' do not appear in my project at all, and when I drag them onto the track (order is correct) I can't place it properly or see the changes. The Legacy Text works however. I'm not sure if the issues are related.
