New Post: Problem with TfsSource Get TaskAction

I am trying to use the following TfsSource MSBuild Task:

<MSBuild.ExtensionPack.VisualStudio.TfsSource TaskAction="Get" ItemPath="$/AProject/ADifferentPath" WorkingDirectory="C:\Projects\SpeedCMMI"> 

However, when I attempt to run this command on my local workstation, I get the following error message:

C:\Code\Build\Local\DevSolutionBuild.proj(40,3): error : Win32Exception: The system cannot find the file specified

I cannot understand how to resolve this issue since I am not completely familiar with how this MSBuild Task wraps the TF.exe command and how it gets around the problem of first mapping a working directory/workspace and then performing the Get/Get Latest Version operation.

Please advise as to how to solve this issue.

Thanks.
