@ DG - Yeah, enough space...went onto the forums on Square, a guy suggested I leave the X1 on with the game in, it will eventually start downloading/installing. Same happened to him, so i took his advice, this morning when i woke up, the game was installed. Not sure when or how long it took, as I inserted the game and restarted my X1 at around 20h30, I went to bed at 23h00 and still nothing happened. So between 23h00 and 05h30 this morning, the game must've decided to download/install.
Not sure why this happenes to some, but at least the game is now ready to play, unfortunately I'm off to work now, so i'll only get to play when i get home
