Arduino A-Star Pololu is not recognized by Windows

Hello,
I got few boards of A Star Pololu which are not recognized by Windows. (only as Leonardo)
When I force it to accept the A-Star driver (under device manager), the IDE doesn't see the board listed, even after trying to "Manage boards", the Pololu is not listed, and I can't load my code . pls advise!
Thanks !
