Adobe Design Std CS6 6.0 MLP AOO License IE FBPA 3 Pack

We bought Adobe Design Std CS6 6.0 MLP AOO License IE FBPA 3 Pack. We downladed the s/w. We installed Adobe Acrobat X Pro on three different machines and activated them also.But after 30 days Acrobat stopped working. Those three machines work offline all the time. What to do now?
