Those pullup/pulldowns should be ok.

Are you sure your 10p JTAG connector pins are wired correctly to the MAX devices?

I use a TerAsic USB Blaster clone on a test board I designed with a 10p JTAG connector and EPM7064S-PLCC44 and EPM7128S-PLCC84 devices and have no JTAG issues with QuartusIIweb 13.0sp1.
