I am trying to D/L a driver off a Dynex website for my cardreader. When I click on it I never see anything in the D/L window that pops up. The manual said to install the driver in the slot but it was a "mini disc" and I understand that they will not work on a IMAC so i try to D/L the driver but it never seems to D/L Am I missing something? Driving me crazy.
