If I open Adobe Live Cycle Designer ES 8.2, which will remove the usage rights, and then simply re-save it and then select "Extend Features in Adobe Reader..." inside Acrobat 9.0, will that that be all that I need to do? I am not seeing any sort of warning message you are referring to. When I open the file ins Acrobat 9.0 and via my web browser, I don't see any sort of error message.
Since your message started with the "The first one seems to be the problematic one." does that mean you don't see any problem with the other two forms?
