hello, sorry for my bad english! I’m new to unreal and I don’t know if this is a newbie mistake, but when I add sound component to an actor with media texture, i mean, with video, and click “play”, the engine crashes. when I play without sound component, it’s all good, the video plays. any help would be great 
It won’t be possible to help you without further details. We need your operating system and a copy of the log file and/or the callstack from CrashReporter.
