Hypothetical question

I've been trying to resolve this on my own but I'm stuck.

reverse engineering software. I've been dealing with this for about 5 weeks now and the situation isn't improving.

This involves original creative work over the past 28 months. I do not have documentation proving my ownership and timeline.

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