i am having a very unlucky week 
i dont know if its a big problem but i need to fix it asap.. i have a compatable cannon SLR camera and flash but suddenly they have stopped working together, my flash isnt broke as i did a test shot, but the camera isnt recognising that the external flash is there, ive cleaned both parts of the flash and camera where they connect but nothing is happening.. the thing is its happened to me twice now this week and as i work everyday doing home portraits my work just swapped my old camera for the same model.. but now its happened again.. is it something i am doing wrong? i havent dropped either of them.. and dose anyone know how much it would be to repair.. thanks for any help xx
