Re-installing my Adobe Acrobat XI on a new laptop

[Mwambi]

Bought my license some years ago. My 7 year old laptop has been retired and am now installing all software on this new one. However, when I have finished installing Acrobat XI and inserted the license number it returns "invalid". Now what?

Thanks!
