Got a denial letter for unemployment, what now?

I was told my separation was for misconduct, which is not what happened. I worked as a hotel front-desk agent before this. The letter lists a deadline and a hearing process, but it is hard to follow. Should I ask someone for free legal help?

Thanks for writing this out. I went through something close to it 10 months ago, and it settled down once I kept a simple log of every call and form.
