Motorola Droid X :: Can't Sync DRM Files With Windows Media Player

I have had my Droid X for about 6 months and until now have been able to sync music to it with no problem. I have a subscription to the Zune Pass so the files that I sync are DRM protected. Windows Media Player is the only software I know of that can successfully sync these files to my phone. That is until recently. While I am still able to syne non-DRM Mp3's, suddenly now when I try to sync any Zune Pass files (which are WMA files), I get an error telling me that the "device's internal clock is not correct". how I can solve the problem but none of them have worked. One suggestion had me go into WMP's Privacy tab in its Tools menu and select the option to "Set clock on devices automatically", but the option was already selected.

How can I check if my device's internal clock is off? What could I have done to mess it up in the first place?
