Fire Particles greyed out

In UE4>Tutorial>Blueprint>Working With Components On Actors… I am trying to make the brazier. Adding the fire (Tutorial Particle System) instead adds an emitter of grey (default texture?) squares.

The Component Browser and the Detail view both show fire. I haven’t begun Cascade tutorial/s yet.

Haven’t changed anything. Have tried on multiple projects: same result.

Using Win7, 64 bit, 4G RAM, latest UE build (yesterdays), integrated Intel graphics. Everything else works fine. Can’t find any reference to this problem elsewhere.
