Quartus problem in Megawizard memory

[Altera_Forum]

While attempting to generate a dual-port memory, I receive the following message: 

"Error: Symbolic name "RAM_MAX_ADDRESS_WIDTH" is used but not defined" .. when the 'altsyncram.tdf' is elaborated.    This has happened before, but only after the files were EDITED, not CREATED: i.e., it worked once, then no more after it was modified.    This particular case won't work even after I re-enter the whole thing under a different name. What might be wrong?  Wade Hassler

I assume you are using a Cyclone III device ?  I generated a Dual-ported Ram with the Megawizard without any poblems. How did you generate your Ram ? With the Meagwizard also ? What are your settings ?
