Wont download, need help cus constant crashing

Whenever I log in to Rph and load onto a character, I always have a chance to disconnect, I know for a fact it isnt my internet because I checked my speeds and its fine, what doesnt make sense is that I left the client on for an entire night on the login screen, and when I checked for it to be downloaded it was still at 0%, is something going on for Rph? Or am I doing something wrong?

factory reset pc

funny, no I wont be doing that.

Is your game actually functioning? If so, clear your cache. Check your config in WTF.

Run only the RPH launcher.

If you are getting the IF/IO error then theres nothing no one can do since its on blizzards end.
