Cyclone III pin assignments problem

You will probably need timing constraints, a black art to non EEs if there ever was one. Google "quartus timing constraint tutorial" or something similar for more information.

It might be helpful to make sure you can successfully build the projects as well as just downloading an already compiled configuration file. Start with a Quartus version used by the tutorial. Once you can do that you will be able to make incremental changes verifying along the way.
