Having problems with multisim 12 wattmeter.

[Niik]

When I add the wattmeter to calculate the PF in multisim 12 ,it can not run the circuit anymore and Convergence Assistant also fails to resolve this problem automatically. However, when I remove it, everything would be fine. I would appreciate any idea to help me resolve this problem.
