MAC Sequoia user here. It started with MusicFab and 'Update Chrome' error messages on Amazon Music, making downloading nearly impossible. Then DVDFab now cannot rip without needing to be repaired constantly and, in the end, not working for ripping. Now Streamfab has error messages on Amazon Prime Video, not allowing for downloads. In all the years I have used DVDFab products, there have ben some expected issues, but folks..... it has never been THIS bad. Is DVDfab nearing the end?
They do make way too many products. For MusicFab, I would suggest a post in the separate MusicFab forum. However, it seems like it has little support.
Same for Dvdfab issues, post in the separate Dvdfab forum section.
As for streamfab, you got the right place, but more detail is needed to even try to figure out what's going on.
Last I checked, Amazon is working in streamfab. With streamfab, as
simchris said, most times can be fixed by deleting the cache folder.
For MusicFab and DVDfab, you can search your computer and see if they have a cache or other temp folders that may need to be deleted, as there could be corrupted files or just be full of junk.
Otherwise, like I said, check those separate forums for issues.
