TS-US keybindings?

Hello all,

I’ve installed Unstable Space on a Windows 7 machine (HP) and the game loads and looks great. However, I find that I cannot call up the “o” menu or communicate with traders/fuelers etc (CTRL-C). The “o” command does nothing while “CTRL-C” advances my contact to the next cyan-colored vessel in the contacts list.

I’m guessing that some keybindings are missing from a configuration file, but I’m not sure which file to try to repair, or what changes
to make. Any advice would be appreciated.
