This has been extremely frustrating.
We like to use motion backgrounds at our church, but the majority of the ones we have (that have worked in the past) crash as soon as we add them.
I have to then go onto one of my other computers (which has a lesser CPU and lesser video card) to delete that background in order for us to be able to edit the presentation in Proclaim.
I have a AMD Radeon HD 6800 video card with up to date drivers. I know that it has something to do with this video card's drivers because I have uninstalled the drivers, opened Proclaim, and it worked fine. I re-installed the drivers after completely removing all of the drivers and it crashed again.
I hope that I can get some help with this soon. Thanks.
