I think it was the original (I downloaded this past friday). Honestly, I assumed that since Windows Media player could do it, the zune software could do it (since I thought they shared the same codecs). If I try to play with it (any of them) with the Zune Software I get that the Zune doesn't support that file (even though it should) and I get the error code C00D1199 (C00D119A). I can't sync the file without the software (though I have not tried to manually drag it in and force the player once it's in the hard drive). I installed the microsoft expression encoder 3 as well because I read it might be a quick fix (it wasn't) and ran a quick windows update. nada. any advice?
