ddr2 sdram controller v8.1

Hi to all,

I used ddr2 sdram controller (classic) in Quartus 2 v8.0 with Cyclone II and it works fine. Now I have update Quartus to v8.1 and in SOPC Builder I don't able to use ddr2 sdram controller (classic), if I click on Add appear the window "Edit module" but the wizard to configure the component no!

I can insert only the "sdram controller".

Where is the mistake??:confused:

Thanks in advance,

Luca
