"unknown error in a block symbol file" with Cyclone III kit

[Altera_Forum]

OK, I am probably just missing something obvious but when I use the MegaWizard manager to create a AltMemPhy component I get this cryptic error message "unknown error in a block symbol file ..." after generating the component. The wierd thing is that if I open the "My_First_FPGA" project that came with the kit I can create this component fine. Does any one have any thoughts as to what this message means? Is there some setting I need to change in a blank project in order to use the memory components?  

 Thanks much

I found the problem. The mega wizard does not work properly when writing to a directory with spaces in the name.

Did you have any weir character in your directory name like "&"? When I tried it, the MegaWizard has no problem with directory like "projects and ip", but "projects & ip" won't work.
