I did a restore and WD loaded with the correct settings without doing anything! However the data on the screen were out of date - they seem to be from the restore date.
Yes WD’s data files (*.inf) are included when Windows creates a system restore point (auto or manual) so if you restore back then WD’s data for the graphs etc will be set to that point in time. I think the logfiles are not included in restore points so if the data is intact and up to date in this month’s logfile you should be able to convert it to datafile and the graphs should be current again
