Hi

Honestly after all the troubles you have had, backup and reinstall.

You're very unlikely to get this fixed via forum help. You'll need someone at your computer to actually see what is going on without the issue of time zones, miscommunication and lack of immediacy.

Upgrades are never guaranteed to be 100% successful and as you had problems before that may have exacerbated the upgrade process and you still have problems then ......

Kind regards
