Hi Loveesh,
To test the problem I made a few new quick slides. Simple animation. No theme. They import and convert in the usual way. I've never had an error message.
If I preview in 'play slide' the animation plays through. If I preview 'next five slides' or 'from this slide' it doesn't. The slide appears but looks frozen. If I click the play button it moves through the first animation. I can play through all the animations on the slide using the play button - one animation at a time. I've tried everything I can think of and have got nowhere. I really need help!
Thanks you,
