Help with Cactus V5s?

Well I got my Cactus V5s in a little bit ago and Ive been playing with them but cant seem to make them work. I have 3 of them (one for the D7000, one for the SB600, and one for a Vivatar 285HV that is on the way). When I put them on the camera and push the shutter button, it will light up the transceivers showing that they are all talking to each other but the SB-600 will not fire. Ive tried everything I can think of, from changing around the transceivers to changing settings in the flash, nothing works. Anyone have an ideas?

I just now found this noted on the side of their customer service page:

Cactus V5 and Nikon SB-600 Speedlight

We have received occasional reports from Cactus V5 customers that they have problem triggering their SB-600 speedlights. Despite the low number of cases reported, Gadget Infinity would like to advise SB-600 users who are thinking to purchase the V5 to hold off your orders. We are investigating on the case and will post an update as soon as we find out the problem. For any questions or concerns please do not hesitate to contact our customer service at service@gadgetinfinity​.com. Thank you!
