Hi

Yes indeed Noels advice is a sound idea . Because you are not certain quite where and when the problem occurred and the many fixes you have tried since, it is best to roll back to a version that worked for you last year . then you need to check that it still works as expected with your Pc build today.
If all is well now try to update to the new version over the top, plus the latest update. It may just be that when you done this last time it installed over a corrupted old version or may have happened during the install so you are working on a bad base.
Just my thoughts,
Mike
