Can't activate my copy of Penumbra

[doojus]

I've been trying to get Penumbra to run without crashing and I've tried uninstalling and reinstalling a few times to different directories because It seems the problem started when I enabled hardware sound in the options the game would just continue to crash. Now when I try to activate my copy it says I exceeded my amount of activations for this key and to contact support, so here I am.

You'll need to contact their support (whichever company you purchased it from) not frictionalgames.

Also; go to mydocuments/penumbra
And delete that folder, that should reset your settings.
