According to the known issues page there are issues with the new product activation screens. What are they? what does it do or not do? (I don't have a copy of the programme with me, but am considering buying it as it is pretty much the only argument for using Windows for anything work-based that I can see).
If I knew what was up then it is possible I or someone else may be able to help. As it is I don't have enough information to make an infomred decision..
