I have a Logitech MX3200 wireless keyboard and mouse set, and keyboard stopped working. I was working with it and it just stopped in the middle of using it.

Some notes:

• The mouse still works flawlessly,
• i've tried to reconnect the KB
• i've tried to reconnect everything, mouse reconnects, keyboard reconnects (or pretends to)
• I've tried to hard reset (holding the connect button on the receiver for 10 seconds).
• I've tried new batteries
• I took out the batteries out of the KB & Mouse and unplugged the receiver over night.
• The media keys still work (launches winamp) but they main keys does not

At this point, i've tried everything I've seen online. I just want to know is my keyboard dead in the water?

I would say it's been about 8 months to a year since i've bought it, and the articles i find on the internet all say that's as long as they last... is this true? what's everyone's experience? I hope it's not true.
