Do you have a mac or pc, as you posted in both forums. If PC it would help to post dxdiag and msinfo, probably using pastebin as a filter, with a link enclosed in code to bypass the trust level problem of posting links at a low trust level.
I had the exact same problem. Tried to reinstall the game, but the dl is going to take 24 hours I guess, so I won’t know if it worked till then. I have pretty good internet speed not great, but I don’t get why it’s throttled back so much.
