Just coming in here to add something to this.

My sister had this problem, all these errors in the title though the last was different.

The game worked fine one day, she logged off, went to be and then the errors.

I went through this whole thread, took all the suggestions (the tech help ticket was no help at all FYI when she submitted one as the response had nothing to do with the problem or it repeated what was here).

I tried every single one on the list. Nothing.

We had to resort to deleting the game, making sure it was all gone. Reinstalled it and she could get in, but the beginning cutscene was so slow it crashed the game. She could not even get past it (and for those interested, if you reinstall the game or just put it in, you are stuck having to watch that long scene before you can log in).

So she had no choice to cancel her sub because she could not get the game to work.

She is dilligent on making sure everything is updated in regards to drivers and .net etc. So I am at a loss and SE is out of another sub from poor customer/tech service.
