You originally stated 1.40.1 server version
The log files you send me show 1.29.2
You can’t switch from using Manual Install of 1.40.1 to Package Center 1.29.2
They are incompatible as of 1.40.0

You can try to Manual Install 1.40.1 again
If it still fails then you’ll need to use FileStation and follow this procedure to copy one of the backups and make it the ‘current’ database
