I used to save new versions of RW separately (after the issues with the upgrade from v.5 to 6, keeping the former one. But today I was careless and installed 7.1over 7.0.4. It crashed. Deleted it and installed 7.0.4 from TimeMachine - doesn’t start. Copied working version of 7.0.4. from second backup and it starts. But it begins uploading in the background and is not working as it used to. :-((
I will get it working again, but I will not trust new versions in the future.
