Question: Error : System is undetermined

Hi everybody.

 

There are several weeks I'm on a school project and for it we need a Maplesim Simulation. It contains a sine voltage (source), a diode bridge (simplify), a condenser and a resistor. The problem is : when I want to simulate it, an error message appears : System is undetermined. I dopn't understand why I've this and from where's the problem...

 

If you could help me asap, it will be very very nice.

 

Have a nice day.
