Tried the new version with my GPU/usb erupter mix. Didn't recognize the GPU and the "-I" switch. Command worked before new version.
BTW running 5870 with 2.4 sdk cat is at 11.12
*update*
tried the new version with my 7970 and the same issue
As my build environment had to be rebuilt from scratch when I returned from overseas, I was missing some stuff which accidentally built the windows binary without GPU support. I've reuploaded a new binary which should work now.
