cRIO setup issue

[brunoUC]

hi, we used to connect our 8 slots cRIO to the the classmate, but recently we changed it for other laptop and we are having some problems while trying to connect the cRIO.
we can see the crio in MAX and we need to reconfigure it with the CompactRIO imaging tool so we can use the labview 2011 on it, but when we press apply the folowing error messege appears:
The cRIO IP address is unreachable. Ensure that one of your computer's network adapters is on the same subnet.
