i don't think so, it happened to me twice at 80%++..have to start back all over again..missed the launch because of this..
what i did later on was make a copy of the origin folder and the download cache folder, look for it in origin settings..
backup as often as u could, close origin before backup..so u don't have to start from scratch if something goes wrong..
nice feeling ehh when u saw the error?

lets just say u r at 47%, exit and close origin, make a backup of ur origin and download cache folders, just copy paste

ok then u'll continue downloading up till example like 65% and there's an error again..

just delete ur original origin folders and replace it with the backup..u'll be back at 47% and there's no need to start from scratch..

omg, it's already step by step bro..can't be much simpler than that

copy the whole origin folder bro, not just the battlefield 3 data
