Lost game code,proof of purchase,email used no longer exists
So I bought the game back in B23 or so,before the Humble Bundle release.
I installed it on my now-fatally-broken previous computer,where I also had the game code saved.
Furthermore,the email I used to buy the game(
[email protected])no longer exists,after everyone in the family moved all our emails to Gmail.
Now the game is out on steam and I do NOT want to have to buy it again.
What now?
