Hello all, and thank you for taking the time to read this. I'm currently running a Canon 7D with two 430ex ii speedlites, and am trying to trigger them both off camera with a wireless hotshoe/fm trigger from CowboyStudio. Spoiler: (Link to product page and troubleshooting video here) NPT-04 Everything seems to be in order except one little problem: the flashes won't fire. I've checked my built in flash settings, and spec'd them as instructed by multiple videos (I'm not sure which ones may be the problem, so I'll provide any settings info on request), I have both flashes set to manual (CowboyStudio specifies this), and am getting a signal from both receivers when I hit the test button on the transmitter (regardless if mounted to the hot shoe on camera or plugged in by wire). The transmitter will even wake the flashes from sleep mode, but won't fire. Does anyone have any idea what could be causing this or any potential solutions? I've been troubleshooting for 2 days now, and am utterly lost. Thanks in advance for any help!
