ModelSim-Altera starter edition can't compile super simple .bdf file

[Altera_Forum]

I am a new student using a Quartus II 10.0 sp1 and ModelSim Altera Starter edition 10.1d. I am attempting to reproduce a lab project I did at school and upon finishing a simple 5 gate logic diagram schematic I go to processing>start compilation. Everything moves forward without problems until the ModelSim software opens. A message appears at the bottom of the ModelSim screen saying "--Compiling architecture structure of file" then nothing happens. In the task panel on the Quartus II screen progress just hangs at 83%. 

 Any ideas what I'm doing wrong? At school this worked just fine except I don't remember ModelSim being part of the process.  Truth be known, I'm not even sure why it is necessary to compile a block diagram file. This is really sort of confusing.

Model Sim doesn't support schematic files ( bdf ). You have to convert it to vhdl to simulate the circuit. Did you write the testbench?

Of course you're right. The problem is that in our lab we use version 9.0 sp1 and I downloaded the wrong version. I tried to search for similar problems but I'm so new that I didn't ask the right questions, otherwise I'd have seen that this issue was addressed many many times in the past. Sorry about that. ;-)

Did you compile the testbench from Quartus or did you make a project on Model Sim?

In our class we're not using ModelSim, but sticking with the old-school vwf. files. My understanding is that ModelSim is way better, but for my purposes I had to uninstall the version of Quartus II I was using and install the old 9.0 sp1 version. 

 Thanks again for answering my question so quickly.
