now i have a black screen and the activation go to offline ( i have turned off windows firewall and antivirus)
If the offline activation page comes out, it can only mean you have a firewall or antivirus still active. Either turn off them, and be sure you don't have multiple firewall running ( for example the default one and a 3rd party one. BOTH should be disabled ), or just go through the offline activation procedure.
notice i have kfll and kdfw already installed and activate this issue hapens only witch klas,klax any suggest?
That's because when you installed these, the firewall/antivirus wasn't interfering, now it is.
