Origin download loop [ Edited ]

[CleanUpNow]

My hard drive recently broke so I had to reinstall everything completly on a different hard drive, but I have an issue with Origin. I have managed to download and install BF3, but for the expansion packs (End Game, Aftermath and Armored Kill only) there seems to be some problems with the download. They keep looping from ~50% all the way back to 5% which is pissing me off since it's the 3rd of 4th time that it happened. I can't complete the download.
