9.10 still supports ZF7363, so it must work. Factory reset AP, than log to AP through SSH , send command: "set director ip xxx.xxx.xxx.xxx" (xxx means ZD IP address, of cause), reboot. Than AP must find ZD. If still unsuccessful, check if it has ZD version software, not SCG version. This you can check from SSH: "get scg", it will get error if it is software for ZD, and scg setting status if it's SCG version.
