The sample script works correctly on our side. Can the problem be reproduced with another project from the same project suite (e.g. the JScript project)? Did you modify the sample script? If yes, please post the code snippet with which the problem occurs. Does the ManualTesting object appear in the auto-completion window (please check that for all the projects)? Finally, please check whether the problem can be reproduced on another machine (if it's possible).
