Hey,
So I'm totally new at this but I managed to fix a very early steam account import issue and I figured if I got it someone else will.
I had a number as my use id on the Http line so following the video on YouTube from Senate I tried importing the number, 'no dice'! so I tried typing in my user id and that didn't work either so I made a custom url in my steam account and then placed that exactly into the Lunchbox steam account downloader and Shas am I'm up and running.
quick post quick fix but I wanted to share to help a gaming community I love!
stay safe!
