Downloading design to Cyclone III board

I am new to Altera and am having trouble getting a tutorial design to download to my board through the USB JTAG cable. The board is a Cyclone III LS development kit and the design comes from the QSYS...

OK, thanks. I think that the tutorial design is for Cyclone III, but not the LS chip. The JTAG and the device did match (EPCL2007807N), but the device in Quartus was set for another Cyclone chip. So when I changed that the design wouldn't compile anymore with the error message (165011) "altmemphy pin placement was unsuccessful".

I looked in the constraints file and did not see pin assignments. It looks like those are handled in pin-planner on Altera devices. Is there documentation on how to migrate pin assignments from one device to another? Assuming I've diagnosed this correctly.

Thanks for your help.
