C# help please for "The debugger could not locate the source file" (likely a broken reference/ path issue)

Question

this afternoon I'm a bit bogged down with trying to run my VS2010 project after moving the solution it's in as well as a couple other projects from the solution. I updated the address strings in the properties window to the new addresses, and of three projects, only one seems to be choking. I get a

• NullReferenceException unhandled exception,

and when I step into it I get

• no source available window,

with the last line in the information given being key:

• "The debugger could not locate the source file 'C:\Documents and Settings\user\Desktop..."

but the address is the original address, as in before the move, and before I updated the directory string property.

Is there another place I need to update this?

FYI The one that runs is a driver... the one that throws the error is a library of my abstract base classes that the driver project uses.

I thought I'd spare the group from pouring over my abstract base class hierarchies if it's a simple setting that is on the nose obvious. Thanks.

Update the Reference to the Project. You cannot simple just copy over the files.
