Really, the message said "Can't find perl script"? I've never seen that message.

What you need to do:

• Paste the actual error message here, in <code></code> tags.
• Post the script here, also in code tags.
• Post the command you used to run the script, in code tags.

There's more that could be useful debugging info, but let's start with that.

Also please read:

Thanks!
