Cannot generate .sof file for CPLD

I've built a simple test project for some new hardware using a MAX II CPLD, but I can't get it to generate a .sof file for programming the device, all I get is a .pof file which isn't any use (I'm using a USB Blaster). Can someone please point out where I'm going wrong.

    the .pof file is the correct file for programming CPLD.

    .sof files are only for SRAM based devices.

    You apparently didn't try to simply program the pof file to the MAX II device. You'll find out that Quartus programmer accepts pof files only for CPLD devices.

    Thanks. I'm more used to the FPGAs and it's a long time since I've used an Altera CPLD.

    I was also confused by the JTAG not working, I subsequently found that I'd assembled the MAX II the wrong way round. 8-(
