Error Device lost after updating firmware

I am trying to test out a recently purchased 1.15 fpga device with an “experimental board 1.3” to power it and the meanwell power supplies that shipped with the devices. I have it connected through windows, associated with the libusb driver, and am using the command line to run FWloader. after running:

java -cp ../../etc/FWLoader.jar FWLoader -c -uu standalone.ihx -ue standalone.ihx  

command (in the usb-fpga-1.15 folder) the device suddenly becomes unrecognized, and apparently has the ID 100:0000. it throws the error: device lost after updating firmware. It does this no matter what firmware file I try to upload.

power cycling the device causes it to be recognized again, but it seems the firmware didnt update.

I am using SDK release 120412 as the latest release was throwing errors in the make process. (having to do with unrecognized characters.)

my OS is windows 7 ultimate sp1
