Mmmm, well, you might try 'disabling' the reader, then 'enabling' it again. Or, uninstall the Reader then reboot the system. A last suggestion would be try to locate an older version of the driver(s) for the Reader, either on back-up discs or even on the Web. Before it just recently died, my Gateway desktop never did get the full Win-10 upgrade, and I suspect one of the reasons was probably because of the card reader issue. It was very annoying to have Microsoft do a partial install (behind the scenes) and cause this issue.
In any case, my Gateway system has been retired and I wish you luck on yours. Nvidia Geforce Go 6100 Driver Windows 10.
