video camera force closing

I have taken videos with the Droid in the past, but the past few days, as soon as i toggle the camera switch UP to capture a video, it gives me a force close screen i have restarted the phone a few times, but same thing..
also, sometimes the camera button does nothing when trying to use it to bring up camera , i have to manually go to drop down list of apps to get to it.. not a HUGE problem, but still a problem when it doesnt do what its made to do...

any help??
