I've lost the script and it shows below error message.
// Write your script here. Note: Reload is disabled upon distribution. Enable by changing the check-box at Settings->Document preferences->Security->Reload.
If an application is reduced/distributed using Publisher, the distributed/reduced one doesn't have the script. You should be able to see the script, if you check the original application (before the distribution/reduction).
As per my understanding, I think you are trying to open the script in distributed application. Try to open the source document where you can get the script.
It would seem to me that you have it is set up to reload and then distribute to the same location,
If this is the case then i would suspect that is has over written the original document with the distributed document. So i would advise to check if you have back ups?
