Silverligh Automation playback issue

I have automated the Silverlight application using IE and while playbacking the scripts, at times am facing an problem like " Object can't find" but the LLP runs as per recorded with very slow moment which takes more time to complete the project than expected. Please refer to the attached Test Log details of the problem I am facing.  As long I investigated, I came to know if the IE already exists before my application launch, this problem comes but even to solve this kind of problem, all my scripts has TestedApps["iexplore"]["Terminate"](); to run before start of the application which helps to close any IE opened, if any. But still I come across those kind of problems. And also, when i run the application from the TestedApps, the application runs fine and if i run that particular scripts individually, the script runs fine. But why do I face those problem???? Please help me to solve this..



If you are in need of any other details regarding this, am pleased to provide you the required details.



Thanks in advance :)
