[Device Not Ready (Medium Not Present) error]

I fixed it! I ended up using a different software, UltraISO, and that worked. thanks so much for bothering to look at my problem!

[Device Not Ready (Medium Not Present) error]

hello everyone! this is my first time trying something like this, so please bear with me! if my problem is ridiculously simple to solve, I'm sorry for troubling anyone, but I'd much appreciate the help!

 

I downloaded a computer game from a torrent (it's in .iso format) and I'm trying to use ImgBurn to write the image file onto a disc (PHILIPS DVD+-RW DVD8631). I keep getting a message that says "Device Not Ready (Medium Not Present)," but I have the blank disc inserted into the drive.

 

Here's a screenshot of my log and the ImgBurn window:

 

Please help!
