I'm looking for advice. I pulled my Mindstorms 8547 kit out of storage and started to play with it after several years of inactivity. 

I found that the Color Sensor, the Ultra Sonic Sensor, and the position read back on motors all do not function. I downloaded the latest software and firmware version 1.31.

Any idea what is going on? Do I need to go back to a previous firmware version to get things to work as they did originally?

Any advice is appreciated, thank you.
