Nothing has changed about moving around.

Maybe verify your gamefiles in Steam to make sure all is installed correctly: right click Medieval Dynasty in the list of games in your Steam library, pick 'installed files' and then 'verify integrity of game files' and afterwards restart your PC.

Other than that, check that your antivirus/firewall isn't blocking anything from the game, Steam or your mouse/keyboard drivers.

If you have a controller plugged in, also try unplugging that one.

Does it work for you after that?
