Trying to use Universal video downloader with the Netflix app. When Netflix starts, universal video downloader app kicks in and prompts "do you want to download" and I click download. Universal Video Downloader starts but then ends up giving me this message

"the app Encountered an error while trying to save the video index file. Please make sure the app has read and write access to this app's bundle directory and try again"

From the message it sounds like it's a permission problem but I'm not sure where the problem is.
