Large Track Crashed Cross

I was at a gig tonight and suffered badly! I played a few random tracks to test the system and set up the sound, and then tried to load a large warm-up mix into Cross, but it totally crashed my PC. I then rebooted, and tried it again with the same results...
Is there an issue with large files/long tracks in Cross?
It was only a 1 hour mix that I use, and it worked perfectly in Cross DJ 1.7 on many of my other gigs.
After 2 rebootd I decided to fall back on my old VDJ system, but I was not happy with it - I prefer Cross so much more, but need reliability when doing live gigs.
I'll try my best to re-create the problem and see if it is just a one-off...
