Have you tried grabbing 2.0b7 again, this time with GetRight?

I read the thread your talking about, I think the file I D/L was thru Getright originally & it seems to work on my older player just fine but to be sure I D/L it again using Getright. Didn't seem to make any difference, problem still occurs. It doesn't matter if it's Consumer/Developer either, the odd thing to me is when trying to reinstall 2.0b7 after this happens the player still freezes once upgrader has rebooted the player
