Need some help with NIOS Tutoral

Hello, I'm trying to start up a project that uses the NIOS processor, and I've been using the Nios II Hardware Development Tutorial (won't let me link it because my post count is too low) to help me get started. I do everything it says on the step-by step instructions but when I start analysis and elaboration (page 28 on pdf) I get the error:

Error: Node instance "auto_hub" instantiates undefined entity "sld_hub"

I have no idea what this means or how to fix it. I've looked around a little bit and figured out that sld_hub has something to do with the jtag uart, I think, and I have no idea what auto_hub is. The jtag uart is pretty important though so I can't really remove it or anything.

I'm using Quartus II 9.1 full version and SPOC builder 9.1 build 222.

If anyone could give me some insight on how to fix this or at least what it means that would be a great help. Thank you.

    I was using a virtual desktop to access the quartus software, but when I went into the actual lab to mess with it, it worked fine. I'm not sure what the deal with that is, but the problem is solved now. Thanks.
