What CAS Interface Studio do you use?!
The last one is "CAS Interface Studio 8.3" no problem with it!!!
Remember that after the first time that you insert "CAS 3" on your PC, you should to do an update for its driver and be carefull because some worms infect CAS 3 driver on "System 32" (Here, you should to format your PC).
