[Wise Care Folder Hider won't hide folder again]

I had been using it to hide a folder on a USB drive from the time I started using Folder Hider until I updated it. Then it no longer would do it. I uninstalled the latest version and installed an older version and I can now again hide a folder on a USB drive without hiding the whole drive.

[Wise Care Folder Hider won't hide folder again]

I updated the Wise Care Folder Hider and now have a big problem.  I un-hid a folder to check some files. Now I get an error Message trying to hide it again. It says :

"Unable to support hiding the files/folders in USB devices,please use the Hide USB Driver Feature."

I had been using this program to hide a folder on that drive for years and now I can't anymore? Why? Can I re-download the earlier version that did work? This is causing a major problem for me...
