Remote Not Working

My remote stopped working after 3 days.  How do I get a replacement?  What can I use in the meantime to navigate on screen?

Replace it where you bought it, or RMA it to WD.

Tried new batteries?

My remote stopped working after about 2 hours.

I pressed the reset button under the unit and everything worked again.

Thanks for all the suggestions.  I tried swithching batteries but it still did not work.  I did not try the reset but unplugged the unit and plugged it back in; all is fine now, the remote is working again.
