How Access Free Adobe Media Encoder

According to what I read, my subscription to Acro Pro DC gives me free access to Adobe Media Encoder. I have downloaded a time-bombed version allowing me just seven days. Forgive this question but I have been unable to find out from Adobe how to proceed (all I get to is a chat window where the support people do not seem even to understand my question). Does anyone know how I should proceed? Just enter an account number? I don't know my account number if there is one - all I have is my Adobe password and Acro Pro DC order number. I ask this so I'll know how much urgency I need to accomplish what I need to get done. Thanks.
