Hey, I bought Penumbra Overture a long long time ago but I never got very far because it freaked me out a little too much

So today I thought I might go back and play it again, but I have NO IDEA where my email/download code/whatever is. I have an old "installkey" file from an old backup of my "My Documents" folder, but I can't find the email or installer anywhere. But, I guess that is my product key.
I'm sure it is somewhere in some old random backup, but in case I cann't find it: Is there any way to get it back?
Sorry if this has been discussed before, but I can't seem to find anything about it anywhere.
Thank you!

You can PM me the email you used when you bought the game or your full name and I can look it up. I checked the mail you used to register here at the forum and there were no purchases on that email.
Yeah, I use a diffrent email for online purchases. I sent you a PM.
I did actually find the email from long ago but the link is no longer valid.

OMG! I found an odd place that I seemed to have moved it to to free up disk space, so I have it again. Unfortunately my default Microsoft graphics drivers in Windows 7 do not support OpenGL very well and the official ones from ATI do not work. I will have to switch to XP, I guess. Thank you very much for your help!
EDIT: Having Penumbra again inspired me to try to force Windows 7 to take the drivers like a man, and I ended up getting it to take them using some stuff from

I have a ATI Radeon X1600, but I am sure this fix works for thier other "legacy" cards. I will be posting a guide on my website soon with exactly what I did if anyone is interested.
