I'm an idiot

I'm a computer newb, and I has a question.

Situation- I downloaded something offa rapidshare, and after it was done, I looked through the pictures.  It opened them in something called Snapfire, or something.  And it did it damn slow.  So I changed what it opened with, and nothing else worked.  So, I tried changing it back to opening with snapfire, but it didn't work.  I think it may be because I changed the entire folder, not the pictures within...

Halp please?

You don't deserve help.

Aww, why not?

Nobody can answer your question unless you state your OS.
