DEP particle tracing for fluid flow COMSOL 4.3 simulation

I've tried to simulate dielectrophoresis by using the particle tracing for fluid flow module of COMSOL 4.3, but I' ve encountered some problems with the dielectrophoresis force.
I am trying to follow the simulation described in the powerpoint presentation, you can find here:
community.cmc.ca/servlet/JiveServlet/download/26656-1179/Particle%20Dielectrophoresis%20Modeling%20in%20COMSOL%204.2a.pptx
but my 3D model is only able to simulate drag force together with the gravity force. If I add the dielectrophoresis force, COMSOL shows me a message of error (Image1.png).
I've tried to simulate the electric field in the frequency domain in a separately Study: COMSOL outputted no errors, but particles remains in their initial position.
So, I choose to simulate in the same Study both the electric field and fluid flow contributions with a stationary solver, however dielectrophoresis force is not taken into account.
Could someone please help me fixing this problem, making my DEP model working?
Thanks in advance,
Selina
