I got a Steam copy of OA, but when it was done downloading and doing the first run installation stuff, my computer froze up and the intallation were canceled. Now when I try to run OA it gets to the BI logo and then gives an error message saying the I have a bad serial number. I've already tried deleting every thing and redownloading it, but that doesn't make the installation things happen again. What could I do to fix this? Nevermind, I fixed it.
