lol you likely just changed what the default program is that you open all files or something like that, very simple to solve but you'll need to take it to someone who knows how to do this if you can't remember what you did

Slow down. It is fixable. But, can you explain in detail exactly what all you were doing? Burning and downloading are two different things. Clicking through things during a burn or install? Not a good idea. Anything could go wrong. What do you mean that all programs open under media player and is unable to download?

Yes i can explain your question
