Remote trigger problem 1000D

Hi Guys

i have a wired remote trigger and a wireless remote trigger for my 1000d, but when i use them to take a picture, the camera focusses, takes the picture, then the screen turns black and the whole camera freezes and won't take any more pictures until i disconnect the trigger.

does anyone have any suggestions? i was going to udate the firmware, but it's running 1.0.7 already.

please help

Thanks

Alex
