I keep trying and i use valid info but it still doesn't work. So can you please make a video?"

I can't make a video, because it's against Cleanfiles' ToS for me to download any of the files myself. However, I can provide instructions for you:

1.) Click the "DOWNLOAD FILE" button. A window will open.
2.) Complete any of the offers or surveys listed.
3.) When the offer/survey is complete, the download will commence!

If you really, really hate surveys, see the following answer: [LINK]
