I just got a 550D and I used my 580EX and 430EXII on it as 'master' and 'slave'. Last night after trying out the flashes on the camera, my pop-up flash suddenly doesn't work (even when forced, in 'Manual' mode). When I go to 'flash control' the camera says that 'external flash is attached' when there isn't one attached.
When I attach a flash, and try to change/clear settings for my external flash, it says it's an incompatible external flash. Both flashes work well on my other canon camera and on the 550D. The only thing is the pop-up flash doesn't want to open up. Please advice. Thanks in advance!
