Complete a software

I have a .Net project which was developed on freelancer (description: https://www.freelancer.com/projects/Java-NET/Photobooth-software-Windows.html ) I have the .msi file and the installer but not the source code, I am having some bugs which are: The application does not open in full screen - When you hover over the start button it displays a blank blue color, change the effect please - The camera doesn’t initiate unless the button is clicked, instead the camera should initiate the moment “start is clicked” or kept on all time even better so it wont take time to start - The countdown timer doesn’t work and it needs a little formatting it’s just a 10 in basic text also make it 6 seconds not 10 - There should be an option to retake another picture if the one you already took is bad - The button in every next screen says “Take a picture” instead of next or finish or so on - In the email input field the text is so small - Back to main menu button is not working and the automatic back to main menu is not working not even after 2 minutes, it should be functional and set to 10 seconds The developer is required to fix these simple errors , deadline is 1 day. I do not know if it is possible to extract the source code from the files , I will send the files upon request.
