SD Card Problem

I finally could add the UP IP SD Card Interface to my project.

But now i get the following error message:

Error: Port "bidir_port_to_and_from_the_SD_CMD" does not exist in macrofunction "u0"

Error: Port "bidir_port_to_and_from_the_SD_DAT" does not exist in macrofunction "u0"

Error: Port "out_port_from_the_SD_CLK" does not exist in macrofunction "u0"

I read the manual "SD_Card_Interface_for_SoPC_Builder.pdf" and there i found the table for the Pin Assignments for DE2. But how can I assign the Pins?

b_SD_cmd --> PIN_Y21

b_SD_dat --> PIN_AD24

b_SD_dat3 --> PIN_AC23

o_SD_clock --> PIN_AD25

Where can I do this?

Thanks for your help :)
