Steinberg Ci2+ with not Cubase essential 5 software

Hi, I have purchase second hand audio card Steinberg Ci2+, but in the box don’t included software Cubase essential 5.
I already write to Steinberg assistance, but not receive answer.
I think resell this audio card only for the problem with software Cubase essential 5, beacuse the audio card is very beauty and comfortable use.
Your are some advice, beacuse up the Steinberg site not present free version of Cubase.
