qmegawiz command line troubles

Hi,

I'm trying to create an altsyncram with the following command:

qmegawiz -silent wizard="RAM: 1-PORT" WIDTH_A=8 WIDTHAD_A=8 myram.v

However, I get the error message:

Error: Incorrect or unknown megafunction RAM: 1-PORT
Error: Megafunction name not known or cannot be found
qmegawiz   <file_name>
   The last argument to qmegawiz should be the file name.
  options:
   -help or -h             Displays this help
   module=<mf_name>        Specifies the megafunction name to create
                           new wrappers from command line
                           Megafunction parameters and ports can
                           be specified in the command line
                           Megafunction name is optional when editing
                           existing wrappers

   -f:<param_file>         Gets parameter assignments and port selections
                           from the given file.
   -p:<working_dir>        Sets the default working directory
Megafunction parameters should be specified in the format <par_name>=<value>
Megafunction port usage can be set as <port>=used or <port>=unused
Optional output files generated by the megawizard can be selected/deselected
through the parameter OPTIONAL_FILES.
   INST                    controls the generation of <variation>_inst.v
   INC                     controls the generation of <variation>.inc
   CMP                     controls the generation of <variation>.cmp

   BB                      controls the generation of <variation>_bb.v
   WAVE                    controls the generation of sample waveform file(s)
                           (wherever the wizard supports it)
   SIM_NETLIST             controls the generation of simulation netlist file
                           (wherever the wizard supports it)
   SYNTH_NETLIST           controls the generation of synthesis netlist file
                           (wherever the wizard supports it)
   ALL                     generates all the applicable optional files
   NONE                    disables the generation of all optional files
The above values when preceded by a '-' disable the generation of the file
Multiple files can be enabled or disabled as shown below
   OPTIONAL_FILES=NONE|INC|CMP enables include and component files only
   OPTIONAL_FILES=ALL|-INC enables all files except include file

However when I try:

qmegawiz -silent wizard="RAM: 1-PORT" myram.v

It seems to create the ram with default values (ie it works). Does anyone know what my problem is?

Thank you,

Kevin
