Halo 5 Installation still an issue

So the other day my external hard drive crapped out on me and I lost all my installed games, no big deal as I just moved the games I had yet to compete or still wanted to play to my internal harddrive. Until I got to halo 5, which won’t let me download passed 5%. Remembering this was an issue when I first got the game I searched the Internet long and hard for a solution only to find that 343i hasn’t come up with one yet 6 MONTHS LATER. I have tried every possible solution that the community has come up with I can’t get it to install, so there goes $250 right down the drain. Screw me right?Honestly at this point I’m just disappointed, I have bought so much halo merchandise over the years and I just feel like this is kind of a spit in the face for the fans. If this is how every halo game from 343 is going to be then I’m not sure if I can continue supporting them, how could it possibly be 6 months after launch and there still be no fix for this issue?
