That code was part of the cause of peoples headaches using the MM. Right now you are using the sleak/tuned version without the fat and more stability than before. Those who couldn't even use the MM prior are having great success with it now.
Look around the forum. I think I saw someone say that if you download the AP6 demo it will install the most recent version of the MM. You won't be able to use acid fully[duh] but I think that this means that since Vegas/acid share MM that you'll then be good to go.
So basically, Sony has a fix, they've prepared a stand-alone update for Media Manager from Vegas 6.0d's MM2.0 to MM2.1 and we are finding out about it from another user and not on the UPDATES page as a MM update? Amazing!
