Walmart song problem - wma.

I just got a c250 for Christmas and when I try and sync the wmas I've purchased from Walmart, it tells me:

It is not possible to obtain device's certificate. Please contact the device manufacturer for a firmware update or for other steps to resolve this problem.

I have the firmware updater on the computer. What's the solution for this?

ILO mp3 player stopped working

1) Disconnect from computer, turn it off, hold in volume + button and reconnect it to your computer - continue holding volume + until the Found Hardware Wizard comes up.

REFORMAT FOR WINDOWS MEDIA PLAYER - Erases Everything: Connect your iLo player to the computer and open Windows Media Player. Click on the Sync tab. Pull down the drop down menu underneath the Sync tab by moving your cursor over the Sync tab and left clicking on the little black arrow underneath the Sync tab. Highlight "ILO 2GB" (wording may vary slightly), and then select "Format." - this should erase everything, and give you a fresh start.

Reformatting songs/mp3 player

The Sandisk site says that your dad's device should play .wav, .mp3 and .wma files. Has the player EVER worked? I got a C250 for my wife as a Christmas present and my computer recognized but refused to communicate with it UNTIL I DOWNLOADED AND INSTALLED THE FIRMWARE UPDATE. The player was a paperweight until then. It turned on and played the demo files pre-loaded on it, but I couldn't transfer a single file into it. Just a thought. Here's the link:
good luck.
