MS Office Professional Plus 2010 opening error

Hi,
Last week I purchased a new MS Office Professional Plus 2010from Microsoft. Then I just installed it in my computer. All of the sudden I am getting this error code 0x8007232B when I open Microsoft Office Professional Plus 2010; it has something to do with activation.
When I entered my product key it did not ask me to activate anything, so I'm not sure why I am getting this error.
