Does it display card information?
You may try to reinstall card drivers manually.
Install new shell, install box drivers, USB drivers...
Then go to C/program files>> Z3x folder>> Card Drivers and install (Setup_W2k_XP) to install card drivers.
And 2nd step: Go to C/program files>> Z3x folder>> Reader Drivers and install (Cypress reader drivers installer)
Hope, this will help
