When attempting to launch a script file, Robo-FTP immediately returns "Unknown or invalid script command. [1099]" without actually executing any of the commands in the script.

The program may report that the error happened on line 1, but line 1 contains an obviously valid command or even a comment.

This can happen when the script file has become corrupted. Sometimes a file system error causes extra unprintable characters to be inserted into the file. This has also been known to happen when transferring a script file as an e-mail attachment. Creating a new script file should solve the problem.
