Hi.
Yesterday, when i bought Papers from Gog, the game was running.
Today, I got a black screen on launch...
From yesterday to today the only change i've made was the installation of Adobe Flash Player for Internet Explore to play Republia Times and 6 degrees of sabotage.

What happened?

I removed adobe flash player 11 but the issue is still alive.

I've solved turning back to a 2 days old restore point in Windows 7... but it's an odd solution.

Anyway, I think it must therefore have something to do with Adobe Flash Player for Internet Explore that has overwitten the version previously installed.
