script closed before i can see the error that occurs?

[wrestlemy69]

Thank you for the explanation. I tried that and it did not work but in a different way. There are a lot of iso in the folder. about 600. That error only come up with about 1 in 5 iso. When I run it, it skipps the ones already done normally. I run it. when it hits an error, I move that iso out of that folder and start again. This time with the changes, I left the iso in there that called issues. It did not skip the done iso this time, and went straight to an error. Different error.
