"Gamer Profile missing" error help

I am wondering why I cannot acquire achievements. I have met all requirements to get the achievement but every time I manage to meet the requirements it pops up with the error message. This is such an inconvenience for me as it does not allow me to acquire
some achievements from several other games. Please help to get this issue fixed as soon as possible.

Thanks

:)

 

Error 803c0008 when trying to play streamed or downloaded episodes in Xbox Video

I purchased full seasons 1 and 2 of Fox's "24" and I'm able to play all episodes on Surface RT. I'm able to download episodes on Xbox as well. Still, trying to play any episode (streamed or downloaded) throws an error "Media Usage Rights Playback Error
The license for this item is missing, corrupted, or doesn't belong to the current profile. To restore the license, sign in to Xbox Live with the profile that originally downloaded the item, then try again. Status code: 803c0008" Refreshing purchase history
doesn't help. In case this is relevant, I'm able to stream my collection in Xbox Music from cloud without any problems. Also, it might be relevant that I'm unable to download purchased on-demand games (i.e. Indigo Prophecy). It correctly shows as purchased
when searched for in games view, has "download again" button enabled, but after downloading 100% it stops with an error "Can't download: Full game - Indigo Prophecy".
