Issue executing loadui-cmd.bat command

I believe the problem was with that particular project. When I created a new project I was able to run it from command prompt (one thing I noticed is, if there is any "space" in the directory name where the project file is stored (e.g. "c:\sample project\ptproj.xml"), the complete path is not considered (only "c:\sample" is considered). Hence, I believe there should not be any spaces in the path specified in Loadui-cmd.bat command)

Even though I was able to successfully run a PT scenario, below error was shown just after the execution started

Should this error bother me? ( as mentioned i was successfully able to complete the execution of the PT scenario.

Thanks.
