You're welcome. Please let me know if you run into any other problems.

The d3d com error just means RTST lost connection to the game. This happens if you alt-tab, change the resolution, or quit. The error will show up and RTST will try to re-establish a connection.

Full-screen is not actually required-- at least it shouldn't be... There's still probably some issues to iron out, thanks for all of your patience.
