why is swtor downloading English video 1?

hey guys!

anyone know what this is about?

i was playing star wars fine a few hours ago then quit out of it due to lag then BOOM has a download to do with downloading english video 1? 

ive never ever had this sort of issue before, ive had many on my other computer but my internet is so slow that this download could take days!

if anyone knows anythin about it please help.

P.S when i try to let it download by itself it says Network error 310 or something, ive looked up this 310 issue and nothing i did helped.
