Could you be more specific please? Which links aren't working for you exactly? I've checked every link, and they're all up-to-date and working for me.
Yes, the Google Drive message about not showing a preview is normal, you should still be able to download it though without any problems. Regarding Gofile, it sounds like the site has been down temporarily. It's online for me now so please try again. I will still add another filehost option, but it may take a while. Uploading now.
And no, you don't have to pay again of course.
