Hypothetical question

I'm in a difficult situation and trying to figure out my next steps.

NDA prevents me from getting new job. I've been dealing with this for about 16 weeks now and the situation isn't improving.

The contract was signed 18 months ago. I am not sure I have the original signed copy. The total amount in dispute is approximately $99,000.

What are the risks if I pursue this? What's the likely timeline?
