That's unfortunate, sorry to hear you still haven't made much progress with this @MusicIan. 
Not sure how much we can do on our end but happy to check just in case if you'd like? I'll drop you a PM and feel free to reply to that if you'd like us to take a look.
Thanks a lot for coming back to give an update on your query. Much appreciated and nice to hear from you.
