Cubase IC pro is not connected to cubase 7

Hello everybody . I have some problem to connect IC pro ( iPad 3 , ver. 9.3.6 ) with Cubase ver 7.0.7 on PC . After reinstall windows 7 (ver. 7601 sp1) IC pro is not see cubase 7 (ver 7.0.7) . everything worked fine before reinstalling. I’m try , I think , all versions SKI remote , but it give no results . In win 7 I’m turn off firewall , open port for IC pro (cubase shows me the port 45000) , antivirus is turn off , but this also give no results . everything was connected via a wi fi router. what could be the problem ? what am I doing wrong? :sob:
Thanks to all .

well . If you say that cubase ic pro will only work from version 8.5, then where can I download cubase ic that will work with cubase 7 ?? I bought the application itself in 2014, who will return the money to me then if it does not work now !?
