How can I prevent Widget Compil Crash

Hi everyone, I have had a really hard time using UE4.6 recently, I’m working on a project in which there is some Widget fairly basics and the engine hard crashes every single time I compil a Widget OR a button I just configured, I’m using blueprints I have some .PNG and JPG as well as some .WAV in them and it’s really annoying It seems I can’t get around this problem and so I can’t get my menus right.
I would apreciate if someone who encountered this issue would lend me a possible solution or if I’m doing something wrong please advise :smiley: thanks in advance.
