You must be on the Yahoo list as well. I'll share my situation with everyone here for those that aren't on the yahoo list.
I had the same problem, but it really was the battery that was bad. Left it in over night in 3 different JB3's with no luck. Tried other batteries in the unit that the battery came with, charged just fine. Finally convinced Creative of that and they told me to send back the battery and they would send me a new one. So, batteries can sometimes be the problem.
Also, the battery can be in either of the 2 bays, it does not matter which one you put it in.
Glad you got it working!
