Thanks H2O Man.
Last night, I unplugged the sensor cable on both ends (circuit board and turbine meter assembly). I then removed the turbine meter, rinsed it out, blew air to ensure the fan was spinning, put it back together. I then plugged the cable back in. Turned on the unit, opened up the pipes, and the flow meter started registering. I did a manual regeneration and I'm now back in business! Saved myself a call to Rainsoft. I've bookmarked the link you sent me so that now I know where to by parts directly if I need them.
