virtual pins in Quartus

[Altera_Forum]

I'm having some issues declaring virtual pins in Quartus II 8.0 SP1 

I have a VHDL file that has 584 pins, intended to be used as a component but I wanted to compile it on it's own to see how much resources it'd use on it's own and to do a small simulation. I open the assignment editor, declare most of these pins to be virtual pins but Quartus still complains about pin numbers not fitting the device on compilation. Is there a setting somewhere I may be missing?

Previous Quartus versions did ignore the virtual pin option in free Webversion. You should get a message about ignored option, however.

Yeah that seems to be the issue. I was sure I had used virtual pins at some point in the past, but evidently not.

I am facing the same problem with version 9.1, although I am also pretty sure that I have used virtual pins in the past. 

Synthesis gives me the following message: Warning: Feature Virtual IO is only available with a valid subscription license. Please purchase a software subscription to gain full access to this feature.  Can anyone confirm if virtual pins are supposed to work with 9.1?
