SOPC Builder Error: "ddsr_sdram: "altmemddr" is not in the library

I'm trying to re-generate the SOPC builder system contents in the Cyclone III NIOS II evaluation kit, and this error appears,

"ddsr_sdram: "altmemddr" is not in the library.

If I configure the FPGA with this design this system works fine, includin DDR becasuse NIOS are using it as main memory.

How is it possible?

    I hate to revive a dead thread, but has anyone ever solved this problem? I am having it too. I thought I can fix it by telling the CPU to use on-board memory but that hasn't worked.

    Thanks
