@Mohikan @simchris Okay. As of right now, the Amazon Music module appears to be working. I have successfully downloaded from being queued, several separately selected random tracks. I have not as yet tried YouTube Music. I have also not encountered the issue with Chrome needs updating bs. But that's merely a matter of time before that reappears!!
If you are still experiencing major issues I would advise doing a 'clean' uninstall using uninstall software like Revo Uninstaller Pro and then following up with CCleaner Professional after the removal of MusicFab, to make sure (all) remnants of the previous installation has been removed off your system. Rebooting your pc and then reinstalling using the 'offline' installer of MusicFab.

In regards to requesting a refund. If you are within your 'trial' period and you want a refund -they have to honour that request. But, be very specific when requesting it. DO NOT give them (any) wiggle room such as: "I put in ticket basically saying, if you don't have a fix, please refund my the purchase price of this module". You'll just be told to download the latest update, or wait for the next update and try again. As you have not been adamant that all you want is your money back. If you want a refund state: I now request a full refund as I am still within my trial period. I expect you to honour this request!
But just know this, MusicFab has never worked properly (as advertised) from it's beginning. It works for a bit then doesn't. It's very glitchy. MusicFab's technical support is garbage, plain and simple. Runaround City basically. I don't even bother using that portal any more, it's more frustration than helpful (personally I think that's by design). Yes, the product is a pain-in-the-arse, but, I'd rather have it than not. Since I've had the license for Amazon Music I have been able to download a lot of tracks, and I do mean 'a lot', so in that respect I have got my original money's worth.
So before acting out of annoyance (justifiable) or sheer frustration (again, completely justifiable) over the lack of usability, try uninstalling (clean) and reinstalling and see how you go. If after that you still find it's not for you -get your money back.
