This is a test patch to try and fix the start up crash, it might work, it might not, this issue is not something we are experiencing out end so can not replicate, and due to it only effecting some people, and the access violation error unreal crash reporter gives is essentially useless information, it is proving very difficult to track down and solve this issue, specially with it being Christmas and if it is an issue with steam itself, they will not be working right now, so we are trying out best!
The start up video and menu background video will have been removed as this could be something related to the crashing, but we dont know.
