Does the card show up in the Device Manager (with a forced installation of the drivers) but will not activate? Doing an install on a fresh drive mounted to the Tempo SATA E4P is especially tricky, as the driver must be manually loaded during the install process. The installation must be done EXACTLY per the instructions provided in the User's Guide. Th error condition encountered is typical of what happens when assumptions are made about the location of the driver. Windows can NEVER search for the driver, it NEVER finds it correctly. It must be navigated to until the file "mvsata.inf" is presented and selected.
