In a situation like this you need to post your circuit file for us to analyze. It is hard to determine just from your desciption as to what would cause this.

This is the default setup and it mirrors my setting. It should simulate just fine using all default settings. Even as I am typing this it is running happily with no errors. You can try what I posted previously. What version do you have?
You may have to try to repair your install. This is the reason I asked the questions. Follow the procedure below. This is the only thing I think might help. I don't know why this problem is occurring other than maybe something got corrupted in your install.
1. Put your CD in your Drive
2 Goto where you installed the program. this is usually C:/Program Files/National Instruments. Open the National Instruments folder.
3 Find the Shared Folder. Open it.
4 Find the NIUninstaller Folder. Open it
5. Find the program labeled "uninst". and click it
6 In the menu that pops up select your product i.e "NI Circuit Design Suite 10" or what ever it is labeled as. Then click repair.
This should repair your install if something has happened that has corrupted it in some way. It will not erase any circuit or project files that you have.
I can't think of anything else other than software files that may have become corrupted or are missing that could cause this. I have tried everything within the simulator to recreate this and the only thing that gives me this error is deleting the power source off the schematic. It is like yours is not recognizing the part for the power source.
This is about all I have on this. I am hoping this solution (even though it is a last resort) will correct the problem.
