you have multiple bots running on port 5001. stop the bot in the gui, close everything, gui, cmd windows, everything. if you run the bot in the gui, start the bot by clicking gunthy-gui exe only. leave the gunthy exe alone. if you run console, and you have been performing any changes using the gui, stop the bot in the gui and close the gui before you hit gunthy exe. if this does ot help you have to investigate if another process is using port 5001, and reasign another port to this process (or kill it if it's not needed). port 5001 must be free to one gunbot only.
