Bought New Hair - Renders now crash

in New Users
I bought this hair:
http://www.daz3d.com/ronya-hair
And every time I load it on a V7 based character (G3F), my renders crash Daz 4.8.
Has anyone had problems with hair causing a crash? Is G3F hair more complex or something? I feel like I wasted $ , because I am afraid to use it now.

Iray?
If so then it is probably one of the items that triggers a bug in the version of Iray in 4.8. The fix is to update to 4.9...
Yes, in Iray. I will try the upgrade. Thank you.
