I upload my project suite. I got some problem in the script test (Unit1) when it's searching for linkMasterTab. The website tested is www.global-erp-solution.com user/pass:jakarta.
According to your Name Mapping scheme, the target link has several parent objects which are not mapped uniquely. I recommend that you enable the Extended Find mapping criteria for the problematic object and move the object to the most stable parent object (pageMainScreen) as a direct child. I recommend that you watch this video for better understanding.
