Hello, i have tried to create a piece of code for my GCSE Computing course work and i have seemed to come across an error that i do not understand how to fix. The codes purpose is to allow the user to book computers for any room listed on the map. But every time i go to make sure that the code i am using works  i get a warning telling me that opening audio input failed, this should not be occurring because i do not have any audio in my program. The emulator then proceeds to run and it all seems to be fine until i go to use the emulator, when i do this i get a connection error or i get the error message "The application MIT AI2 Companion has stopped unexpectedly. Please try again. What would be causing this issue?If you would like a screenshot of my code then please do not hesitate to ask.
