Hello,
Unless you are using some cache (such as an op-code that doesn't refresh automatically scripts when they change) that makes no sense.
We don't know what could be wrong on your server; maybe you don't have write access to the output file, or you are trying to open an already opened document (and the app doesn't refresh the content if it's already open), or you don't have changed/saved the script or any other unknown issue.
As you are using a trial package, we recommend you to follow the practical guide and check the included samples and your server logs.
Regards.
