Could you please try updating your Unity version to 6.4?

yes, i can try to update the version of Unity

ok I updated unity, now i have to install only Convai SDK 4.4.0 or also NCP AI Engine?

i installed SDK from asset store but i have this problem now

It looks like you are using the UPM version.

Please remove all Convai SDK-related files from your project and make sure there are no old Convai files remaining. Then install the SDK again. NPC AI Engine - Dialog, actions, voice and lipsync - Convai | Behavior AI | Unity Asset Store

Mixing old SDK files with the current version can cause unexpected issues.
