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
