Yeah, I'm done

I managed to fix my issue 5 days ago, though I have yet to restore my subscription.

This was the blue reply to a thread about this error in Technical Support:

So what I did was:

  1. Go to Device Manager and check your graphics driver under Display Adapters
  2. Go to the AMD website
  3. Look for your exact Graphics driver and download and install the version for your OS

It took a few tries for me but it worked eventually, and I haven’t had any problems with logging in since. Good luck.
