Hi,
using .pof files means you are programming over dedicated AS interface. Most designs are now using .jic programming over JTAG interface. You can simply open the .pof file in any version of Standalone programmer, I expect that it should be able to program EPCS4 and EPCQ4A as well.

If it doesn't work with EPCQ4A because programmer is performing additional checks of flash type (which won't be actually necessary in this case), you'd need an original .sof file to generate a new .pof or .jic without recompiling the design.
