Nios Problem

you have changed the device but keept the footprint ?

you should check which pins have no exact pin location assignments

if you have the chance to get access to the version with the prious device, open the project, go under menue -> Project -> organize quartus II settings file and exit this project. now your qsf file is sorted.

You will find a section labled as

# Pin & Location Assignments

# ==========================

with all the location assignments, you can copy this into you actual qsf and replace the assignsments there

you will also find some other sections for the fitter and pin functionality if used like current strength or fast output assignments, you should also copy them.
