Its always good to provide the basics of your system when posting about an error.
Some general handy tips that may or may not resolve your issue would be
1 – trash your preferences
2 – clean your cache
3 – if you’re on Mavericks, update to the latest 10.9.4.
4 – if you have an nvidia card, update to the latest CUDA (if you’re using it)
