how the hell do i use the "track 1" cdrwin makes??!

yo. Im trying to make a backup of my worms armageddon cd. I used the backup cd function on cdrwin beta 4. When it was finally done, there was one file on the cd, track01.cda...?! what the hell, how do I use that? It thinks it a real audio file, when I double click it just says data file in realjukebox, i know its not supposed to open there. All I really want is a no-cd crack, but none work so I've resorted to trying to burn a copy. Please help...thanks.

#### man, i guess thats what i get for using a ###gen. those goldenhawk ba####ds
