SW Rx says my driver is out of date.  I am running an Nvidia K4000 graphics card.  The recommended driver is 431.02, and I have installed this driver.  Rx still says my driver is out of date and that my current driver is 26.21.14.3102  

The last five digits of the current driver are the same as the recommend driver except for the location of the decimal point.

Why do I keep getting this error?
