SoftGrid Error : virtual environment name has changed

When Launching an SoftGrid App-V application i receieved the following error message.

"The SoftGrid Client could not launch the application you requested.
The SoftGrid Client could not use the specified OSD File because the virtual environment name has changed. Please report the following error code to your System Administrator."

Resolution:
I had taken a copy of a existing package and despite performing a FILE SAVE AS and selecting new Pacakge, the OSD file still had the same application name inside. The NAME="" inside the OSD file must be unique. I changed this to my new application name and it launched fine.
