Me too. I had 328 days to update, so I changed to "alternative download method". Immediately it downloaded 90%, then stopped. I'm getting o.03 mb/s at the moment. Yesterday, it took me 4 hours to download it using both methods.
What's worse, when I play, it's taking 3 minutes to do each jump, and I can go and make a cup of tea if I want to open the galaxy map or mission board. What's going on, Frontier? It didn't used to be like that. It's not good enough. Playing the game isn't enjoyable like that. It makes me want to pull my hair out, except I don't have any.
