one of my two is unlocked, I requested the developer key for the other

unfortuantly neither machine is acting up for me today. I'm going to avoid 
doing any updates for several days in the hope that this ends up being 
repeatable. I shrugged off the firsttwo machines having a problem, but 
after seeing all four that got upgraded act up within a day or so I 
decided to speakup.

If I can repeat the problem I'll try it.
