I've tried all caps in the license key, no hyphens, no caps, no spaces. I've tried both my emails & not just my paypal email & it just says my license key is invalid. I've never given my key to anyone, and nobody else bought the game for me. I would really like to change my username & be able to play the game thru steam so any help would be greatly appreciated.
Thanks in advance
If you still have your license.ini in your Documents\Piboso, copy paste it from there. The format should be
X1X11-Y2Y22-DF5G6-A99B2-C33D5
As for the email, it's the email associated to the email that you used to buy the game.
If that doesn't work, you should PM Piboso here.
