This circuit has no power sources: unable to determine the simulation timestep automatically.

Yes, another one of these errors.

 

I am running Windows XP in Oracle VirtualBox.  I have installed Multisim 11.  This worked just fine up until i deleted the virtual Windows XP and reinstalled it... When I installed multisim again, I have continuously gotten this error:

 

 

This circuit has no power sources: unable to determine the simulation timestep automatically.
Add a power source or set the simulation timestep under "Interactive Simulation Settings" to proceed.

The circuit I have set up is VERY simple... a DC Power source, a resistor and a ground, but I still get the same error above.  I have uninstalled multisim and reinstalled it.  I have deleted user config files.  I have tried repairing the program.  I have updated the program.  I even removed the virtual windows again and installed it again.  Nothing.

 

I have searched these forums and seen that others have gotten this same error, but there has not been a solid solution that has worked for me.  So I am throwing this same problem up again, and hopefully there has been a solution that I have over looked, or maybe how to setup the time step properly or something...

 

Thanks for your time, and ANY further information you require, just let me know... like I said... just a real simple circuit and I get the same error... I have tried using example circuits on the cd from my troubleshooting book... still get the same error...

 

Jim!
