Error when generating DE1_system SOPC

Hello,

I am working on MODULE 5 of the Embedded System Lab instruction v91 (November 2009, v 7.0) found in the Altera Wiki.

I am using Quartus V10.1. I have installed the UP_IP_Library.

I have completed the definition of the SOPC system for the DE1 as described in module 4 of the lab and the system was generated succesfully.

When trying to compile the system, I get the following messages:

Error: Node instance "auto_inst" instantiates undefined entity "cos_Approximator_GND3CNA6YR"

Error: Node instance "auto_inst" instantiates undefined entity "de1_vga_dma_GN6XXUQOV3"

Error: Node instance "auto_inst" instantiates undefined entity "phase_Generator_GN4TFERVBC"

Any help would be greatly appreciated.

Happy new year every one

    Error: Node instance "alt_vip_cpr_0" instantiates undefined entity "alt_vip_cpr_GNIXHWNATI"

    Error: Node instance "alt_vip_crs_0" instantiates undefined entity "alt_vip_crs_GNWMDRIE35"
