A posting on AUGI that I have had confirmed from Autodesk states:-
"We know that the advertising is already published on Subscription Center. However the advantage pack will be available only on the 23rd of November 2009.
We are really sorry for the confusion.
Have a good day!
Autodesk Business Center"
The Pack also needs to be translated into other EMEA languages (French, Italian, German, etc.) and that’s why the local office wants to launch all the EMEA languages (English, French, Italian, German, etc.) all together at the same date.
Lets hope by then all the bugs and missing content has also been totally fixed!
