Downloading without using steam

I bought the game before it went onto Steam and I have in in Steam on my computer at home. My question is that I want to play the game on my work computer but I cannot use steam because of my work's network blocking the connection. Is there a way I can play the game at work without steam?


P.S.
And by the way before anyone says "There is a reason your work blocks steam" or "you should not be playing games at work anyway" I don't care I love playing BeamNG Drive so much that I don't care!...
