add-price-quotes - windows command line

[tstalker at word-builder.com]

I've been trying to get the add-price-quotes command to work in my  
gnucash program on my Windows XP computer. The file I need to run is  
on a different hard drive from the program. Via the command line, I  
navigate to C:\Program Files\gnucash\bin, where I run gnucash  
--add-price-quotes H:\My Documents\Finances\software\gnucash\test

test is the name of the file. I get a runtime error that I can't  
remember now here at work, but I tried the syntax of the command  
differently, using $HOME\path-file, reversing the slashes in the path,  
all multiple times.

Same thing.

Then I quit gnucash and tried running the command as well. Same thing.

Then I tried updating prices from GUI. Would run but wouldn't update  
prices. I think because I had already updated them from the GUI earlier.

Is there a way to run the price editor auto updates by not using the  
command line? Does the file have to reside on the same hard drive? How  
can I make a cron job in Windows to update at a certain time?

I'm rather comfortable with the command line on Unix but not in  
Windows. I never use the terminal in Windows to do anything.

Thanks, all
