My friend and I started doing EA Active 2 together for fun awhile back.
It's been a couple of months, and we noticed that one of the leg sensors doesn't want to work anymore; one of the batteries apparently exploded inside of it, so I cleaned it out and washed it, then replaced the batteries. Now it at least turns on, but even during re-calibration, it doesn't seem to want to be detected by either of the USB sensors.
Is there an easy way to replace it? --- My weakness is strong!
