For the Bot defaults to work at the end you have to wait for the next OSBot client release
It is trying to set Shift drop and Esc Key but there is a small bug that prevents osbot from scrolling in the settings tab atm, which should be solved in the next release ^^
There is no connection limit to OSBot when you have VIP, so no idea why the screen is black or why you get the connection error, never even seen that before.
Nothing to do with the script though, that's the client
