Well...maybe this will answer. I just had a reqeust for a re-install of MediaLab. So this time, I went out to the SITE, and specifically downloaded the v2008, and installed that.
I then sent in the 'M8' code (instead of the 'M6' codes I had been generating); and was given a proper License Code. So far, I have not received any indicating problems.
(Keeping my fingers crossed)
