I've started receiving this error (C00D1365) when I try to play certain albums in my music collection. I spoke with Zune support who had me log out and back in and then suggested I reinstall the Zune software.
To me, that suggestion makes absolutely no sense and seems to be based in "Well, I don't know what to do so I'll tell him to reinstall the software". I'm hoping for a more educated response, something that hints at intelligence and knowledge. If reinstalling the software is honestly the only way to fix this problem then I'll do it, but as a computer professional I can't see any way that reinstalling the software would do anything that the kiddies over at Microsoft couldn't do on their end.
Wow, all this right after I bragged to a friend I'd never had a problem with MS's DRM.
