Sazman55 on EZ Drummer 2 compatibility with Cubasis

Is ED2 compatible with my version of Cubasis VST us-428, I down loaded ED2 and it doesn't seem to sync with the cubasis software. I have a Tascam us122 interface with it. I copy pasted the ED2 dll file into the cubasis folder, but can not find anywhere in cubasis where to launch ED2. Can you help?!!! Thanks
