HELP!!! SYSTEM CRASHES.....EVERY Night

[Broman]

this happened the first night I used the program. The second show was fine.........but every show after it that it has locked up at least once. I have to shut the computer off......reboot..everything stays as is (i.e the song list and singers) and then it's fine again. Though last night it did freeze twice.....2nd time 6 songs after reboot. Everything else as I said works fine.....PCDJ....etc. Please advise as to next step. thanks
