Package Validation Error : The Package Designer Deletes The Code From Script Task.

While Creating a script task in Control Flow, I am getting "Package Validation Error". Here is the complete message:

Error at Validate File and Load Data: The task is configured to pre-compile the script, but binary code is not found. Please visit the IDE in Script Task Editor by clicking Design Script button to cause binary code to be generated.
(Microsoft.DataTransformationServices.VsIntegration)

As mentioned in the message, I opened the script IDE and added the code I need. When I close the VSA IDE, package designer displays the same error message.

The worst part of whole story is that if I close the package designer and reopen it, I find that all the code I wrote in the script task has been deleted by the package designer. This is not at all acceptable as I saved the package the and still lost all my work. I did all the coding from scratch for that task.

Please respond if anyone faced similar problem.

Thanks in advance!
