creating company files

SUGGESTED

Hi guys, can somebody help me with my issue?  apparently when I downloaded the sage 50 accounting 2020,  I ignored to select  create a new company and now that I am going to do receivable and payables set-up lesson I cannot do it.  When I open Sage software it will bring me to Sagedata20 instead of the welcome and select company window  What shall I do?
