I have edited my workflow, I was able to save and publish the workflow fine yesterday, but after making some additions to the workflow today I am able to save the workflow but not publish it.

The error message I'm getting is:

"nintex failed to publish workflow error in the application"

...or something along those lines.

I have read about breaking the workflow down and i have removed steps. I have also disabled action steps and the same message appears. 

Any help would be great, I'm on a deadline!
