iRiver H320 doesn't work after battery install

[Pirato]

My iRiver H320's battery recently ran down, and would no longer hold a charge. The last time I played it, it died in about 2 hours. So, I bought a new battery, and very carefully changed it, following some step-by-step videos I found on the web.

Although I took great care to follow all of the instructions exactly, the iRiver doesn't work anymore. It won't turn on, and when I plug it into the computer, it's not recognized as a hard drive. When I plug it into the recharger, I get the iRiver boot screen and "Charging..." screen, but no matter how long I leave it plugged it, it never gets finished charging.

Is it possible I plugged the battery in wrong? I have the red wire at the top and the black at the bottom. I made sure that the battery was firmly plugged in, too. The new battery is 1700 mAh where the old one was 2200 mAh, but as far as I can tell, that only affects battery strength (i.e. how long the battery holds a charge). What could I have done wrong?
