Got a denial letter for unemployment, what now? - 5 months and counting

I was told my separation was for misconduct, which is not what happened. I have read a lot of threads here and could not find my exact situation. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

I printed my emails in order and wrote a one-page timeline. The hearing officer kept going back to it.
