Yes, I have Windows 64bit. I tried to install both versions of the drivers and run the game.
When installing the drivers, the system told me that I have drivers that are newer. The game never starts. The download screen appears for a couple of seconds, and then Avorion just hangs. Nothing has changed, the error is the same. Here are the logs.
