Hey, have you checked the file exists//is created by the program? Basically you need to narrow down the error to a specific function call. If you can't do that then i suggest you go about changing your script to include the File.exists function to check that it exists, then that you can open it, etc. (Examples here:

Also are you running this straight from your IDE? It could be a local permissions problem because of that, run it from the command line (making sure it's your user's session).
Cheers,
Jamey
