ModelSim PE Student 10.3d: error loading design vsim-3170

[Andy W]

Hi,

For a simple edge detector project, here's what happens in the console after I do "Simulation - Start Simulation":

** Error: (vsim-3170) Could not find '<mypath..>/edgedetector/work.edgedet(behav)'.
# 
# Error loading design

I've also posted a more detailed explanation on stackoverflow:

Thank you for considering my request.
