[Dxbase] DxBase 2007 and vista problem

[n8dc-8 at comcast.net]

New laptop running Vista .. I loaded up dxbase and of course it was in trial mode and the host file wasnt there but I figured id do that last. I added my registration to the registry and now it comes up and if i tell it to go to my mbd file it just closes?.. If i tell it to use the trial mbd file it tells me its the wrong version ? When the program starts the dxbase welcome screen says its registered to me so whats going on here ... It all works on my y desk top ? All the same files my desk top is also running Vista.. I even tried uninstalling and reinstalling but same thing .
