So, after downloading the game I waited for the other download to finish. As soon as it did I tried logging in. I waited for an hour and I still couldn't get in! So I deleted it from my computer and tried the whole entire thing again. Same thing happened! I've tried this at least 4 times now and I still get the same results! Does anyone know what the problem could be?

I'm not sure what the problem could be, but perhaps residual files which are glitched are still present within you computer and screwing up your redownloads. You could also try obtaining a full file of the game files rather than using the ingame downloader/patch.

You could try following Gothic Kitty's fix to see if it'll help but other than that I can't really say.
