Bus Blaster v4.1a fails self test

I recently purchased a bus blaster v4.1a from seeed studios, and kept having errors uploading attempting to upload buffers to the CPLD using urjtag (the modified version from here, and also the latest from their git). I keep getting TDO stuck at 0, and svf: chain without any parts.

I then ran a self test following the instructions here: http://dangerousprototypes.com/docs/Bus ... _resources, connecting the terminals using bus wire. The LED is lit. This is the results of the self test:



This result is constant. What can be done?
