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.
You don't actually need to install the demo either.
Download Acid Pro 6 Trial. Run the acidpro60-trial.exe file and let it expand the setup files to C:\Program Files\Sony Setup\ACID Pro 6.0\ and then cancel the installation.
You'll find a C:\Program Files\Sony Setup\ACID Pro 6.0\mediamgr directory where you can run setup.exe and install just MM2.1.
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!
I had MM2.0 . I know I had it there but NOT enabled. I left it installed just so I could demonstrate how it would crash Vegas when enabled - so I know it was still installed.
Now, Grobsie, all I did was to install AP6 and MM2.1 came along. I did NOT uninstall MM2.0, I just did the install of AP6 - and MM2.1 was there.
