Hey Nomad, it's no problem at all! It's possible you downloaded it from IndieDB. The indie DB version isn't being updated anymore.
I should have sent you a kickstarter message with a link to redeem your copy of Vigilantes. Let me know if I somehow missed you, and let me know your KS name. You just need to enter this link in your browser, and enter your email address (preferably the one your humble account is linked to, if you have one). After that, if Vigilantes doesn't show up in your humble account, try doing this to claim it:
1) Go to purchases
2) At top, you should see "You have unclaimed purchases"
3) Click down arrow beside this text
4) Vigilantes should appear in this list
5) Press Claim Order
Let me know if you encounter any problems!
