Clean install for me too. I can't see how there is any difference in box to DL. Same file, just burned on a disk for you.  Looking for excusses where there are none. Tec admits to the problem, why is that hard to understand. Ordering a box set now may not have been a wise decision. Once you open it you are stuck with the bad version and even when the fixed version is released, your still stuck with that bad version as your main box disk. Now that is something I can't understand. Oh well, it's not my money.

I have done a clean install of the second to last pre-release and everything works as it should and soooo  much faster. All it will cost me is a new disk and the time it takes to burn it when the fixed version is released.
