Try to remember what that other program was and make sure it and the media creator didnt automatically get downloaded again
If youre sure they arent installed:
Go to the start menu and type device manager
Find your DVD drive in that list under DVD/CD-ROM Drives
Right click it and click Update drivers, if it says they are up to date, right click and uninstall the drivers
After they are uninstalled the drive will move to a new area of the device manager list, so keep track of what was there to find it again
Right click it and click install drivers, let it find the drivers automatically (or just restart after the drivers are uninstalled, windows should try to install the drivers automatically once it boots)

Once the drivers are installed try using it again, if there is no change you can try uninstalling the drivers again, but this time manually select the drivers from a list, just go in order down the list, install the dvd drivers, uninstall if it doesnt work, repeat until it does work or until you run out of drivers to try
If nothing works then the drive really is faulty and youll need a new one, if its still in warranty it would be easier to not bother with any of this and just give it to them to fix for you
