There is another solution for programming ES devices that allows you to use the latest version of Quartus (7.2).
Go to the project directory, and open the .qsf file. Make the modification as shown below:
set_global_assignment -name DEVICE EPM1270F256C5
to
set_global_assignment -name DEVICE EPM1270F256C5ES
Then, save the .qsf file and compile the project as usual and finally program the “ES” device with the new generated .pof file.
You may not be using the 1270 device, but the main point is that you need to append "ES" the the device name.

I know this is an old thread, but I just wanted to resurrect it and say how much I appreciated this tip.. I'm using an old StratixII eval board for a real quick demonstration and had the same problems of getting the MaxII-ES chip on the eval board programmed... I already have Quartus 6.1 and 7.2 on my machine and wasn't looking forward to installing yet another version (from an earlier suggestion) .. this tip however to modify the .qsf file was a nice, easy, clean, simple way to get things moving forward...
Thanks wahilakn!
