I have bought Clickteam Fusion 2.5 with UWP export on Humble Bundle. I'm trying to register, but I don't have a serial number because the version I have is for Steam. Because of this, I entered my Steam info and the error says "This profile was not found - please see the note below for instructions on which information to enter here". My profile is zvoc47 and I tried entering zvoc47 and the steamcommunity link (I cannot say it due to the limitation for newbies), but no success. What am I doing wrong?
