iStopMotion v3 fails to launch

I’ve just installed iStopMotion v3 on iMac running 10.7.5 – and it fails to launch. I’ve installed on 3 computers. None will run iStopMotion. The Apple error dialog about failing launch appears every time. Thoughts?

Oddly – last week I did the initial install and it worked fine. In the meantime there’ve been a couple of Apple updates. Have they done something to prevent iStopMotion from launching?

Thanks

I have the same problem. Seems like 10.7.5 is the problem. I wrote to Boinx and got this answer:
Apple enabled a broken version of Gatekeeper in OS X 10.7.5 so about every sandboxing enabled app will crash on 10.7.5. We are talking to Apple about this at the moment. The bad news is: Right now there is nothing we can do about it.

You can wait for an update or upgrade to 10.8.

We worked hard on this and finally found the problem and a solution to get around the bug. Please download the current iStopMotion application again from our server here: http://www.boinx.com/download/#istopmotion
