MudBox MAC OS X Lion "RESTORE WINDOWS" problem

[des.k]

I tried to install Mudbox a couple of times and it stalled during activation first time, then stalled during opening a tutorial movie on screen. 

I tried to re-install AGAIN, then started getting this error: "The application “Mudbox” was forced to quit while trying to restore its windows.  Do you want to try to restore its windows again?"

every time I click on either option, nothing happens and box just re-appears, until I force quit. 

suggestions?
