You could always mount it using a program like Alcahol 120% or Daemon Tools which is free

.
Daemon Tools
Just install it, once its installed you get a new icon in your task bar (near the time) right click it go to "virtual CD/DVD rom" then choose how many drives you want (1 will do for now). Then you'll notice that drive has a sub option on it to "mount image", click it, then mount the .cue file and it will play.
