Software Update For Range

I just got the software update to add back the range after the "temporary" software adjustment was made to avoid fires. I'm only getting 210 miles in range when before I got anywhere from 235 to 245. Also, and this is my biggest concern, the car stopped charging! The green light was totally off and the L2 charger TROUBLE red light was flashing. The display on the dashboard read: "Charger Override/Interrupt Occurred." I've called the dealer but have not gotten a satisfactory answer. Any ideas? Has anybody else had problems with the software fix?

I found this. It's for the Volt but probably it applies.

The software update shouldn't change your actual range. Remember the GOM is an estimate and will go up and down depending on a lot of factors.
It looks like it might have affected charge time, though.
