Guys in all fairness this isn't something you can "test". It's a problem with steam keys, one of their webpages, and their database. The reason you can buy it on steam is it's linked IN steam. For those of us NOT in steam, you do remember we can still play the game right? Just download from their website and relax. They'll get it fixed.

I contacted the devs directly yesterday when the email came out, as there is a bug going on with the php steamkey page and sql (they're getting some deadlock code). They thought they had it fixed yesterday, but to no avail. Logging in today, the entire Steam section of the profile is missing, so I'm assuming whatever happened messed up bad enough they are trying to figure out the right way to fix it before others keep on using it. If I hear back before they tell everyone what's up, I'll let everyone know.
