Did you re-enter your licence key? Generally, after an OS upgrade, I lose ALL my registration keys (I think they are kept in the Content Store database) and have to re-enter all of them and all of my custom settings.
Some applications don't store the registration info in the same way, and so for those I don't lose my registration info, but for all the rest, I do.
