Hi all, I've got a Wiired & Wireless Twin1 R3-UT wireless shutter release that I've been using on my 40D. Up until today it's been working fine... but then suddenly, nothing... Both batteries are fine, and the trigger (hand held bit) is clearly working as it flashes white when I press the button. So I think the problem is with the bit that goes into the camera... it's not triggering the shutter... It doesn't flash or do anything (I can't remember whether it did before or not, when it recieved a signal). I waited ages to get one of these, as it is very difficult to buy camera equipment where I live... hence I am a bit gutted that it is not working. Unfortunatley it is not as easy as getting another one shipped from the US. So, I'm wondering if anyone has any suggestions as to how to get it working again... it might just be a simple fixable thing, afterall. I was wondering about taking the screws out and looking inside, but as I'm not a very technical girl, I don't know if this is a good idea or now. Any suggestions please...?
