Modelsim Simulator Error & Request about solutions and source files

I have a two questions.

First,

I use the quartus 18.1 version and run gate level simulation using VWF.

I can see the simulation waveform result but in this waveform the delay isn't considered. The output signal has a 0ns delay.

During simulation log,

The "Error: can't read "FileWatch(filename)": no such element in array" message was shown.

What does this message mean? Can it occur the 0ns delay problem?

Second,

I requested the solutions and source files about lab in this page (Solution Request for Intel® FPGA Academic Program) about 10 days ago.

But I didn't get any response.

Next semester, I will teach the subject using Intel FPGA training kit which

has the Cyclone II and V.

I need the solutions and source files about courses ASAP.

Thanks.
