Any fix to Error 10099 after months??

Even after the most recent patch, I cannot start PTCGL on PC. It has been MONTHS and I cannot login - despite being told by support when I first encountered this issue that it was a known problem that would be fixed soon, and presumably issues that prevent a user from launching the game is a high-priority fix. Some transparency about this issue and why it's so persistent would be very reassuring to me and other users who are multiple months into being unable to use Live on their computers.

Also, for some reason, since the patch, the issue crops up on step 10/39 for me instead of step 9/39. No idea if that's relevant.
