Smoke Flow Error

I was trying to make a smoke simulation, but when I made the flow object, the default smoke particles system didn’t appear. When I tried using the quick effects smoke instead I got the following message:
Traceback (most recent call last):
File “/usr/lib/blender/2.64/scripts/startup/bl_operators/object_quick_effects.py”, line 331, in execute
psys = obj.particle_systems[-1]
IndexError: bpy_prop_collection[-1]: out of range.

location: <unknown location>:-1

The other quick effects work just fine. I’m kind of new to blender so I don’t really know much about the scripts yet.
Can someone please help?
