iStopMotion can do a preview but not insert picture in the timeline

Hi,

I’m using the last iStopMotion Pro on a MacBook Air with Mac OS X 10.7.4 and a Nikon J1.
I don’t understand why, but iStopMotion can make a preview. No problem, picture is just amazing.

But when I want to start a timelaps (every 30, 45 or 60 sec) I get an error : (iStopMotion) can’t insert the picture in the timeline.

Do you know why? Please help us

Hi, i am also interested for the answer because i have also this type of problem. but i can’t make a preview too. venturiautomobiles, how do you configure your nikon J1 for do that ? thanks
