Album/artist scrapers not working properly

[SSThing]

I have managed to update my box eventually to custom 209.
 This version certainly seems to run better than "official", boot up and connection to my network are quicker and more stable. Most importantly, apps that PlayStore reported as incompatible on"official" have now installed in this version 
BUT... I cannot get my music library to correctly show album covers etc. Where there is artwork etc in the folder there is no problem but I cannot get the scrapers to correctly identify many of the files. I have tried the different information providers and also several Kodi versions including Leia but whenever I try to scan nothing extra appears. This is not confined to obscure artists etc.
Does anyone have any suggestions please as this was working fine on v201 and I really don't want the hassle of downgrading?
Thanks

I decided to go directly to the Audio dB website to make sure that the albums I have trouble with are actually on there. Via my Android tablet I have registered and the information I need is all there (as I suspected it was).
As time consuming as it is going to be, I decided that I would find the info for the problematic albums manually and then just save the covers directly to the appropriate folder.
BUT.... from my Q10pro, I am unable to access the website, I keep getting an error "key chain has stopped" and Chrome closes. Every time. I have cleared caches and reinstalled Chrome but the error persists. I am sure this is no coincidence as Kodi access to the database isn't working either.
Any suggestions?
