I downloaded 4kdown to get higher resolution videoclips but it stopped giving me variety of quality choices. It should be given the oprion to check presence and chose otherwise 4kdown is useless for me at least.

I downloaded the 4kdown in order to get access to the versions of the videoclips in HD but over the time it stopped giving me choice between the quality versions on youtube (but I see with the firefox plugin that there are different versions). How could I get control over the 4kdown (to select the proper video quality)? It is useless for me without this feature even in free version of it (I'd be agre to buy but it doesn't work).
