Captions disappears

Hi! I have several times had a bug/error where the captions/text are not visible in the preview. If I adjust the size of the captions to about 380(very big) the text is visible and ofcourse way to big. But if I try to change the size in any direction it disappears fast and you can't se the caption at all. I've added a photo of how big the captions have to be to be shown, lower och bigger than that and they disappear.

I have tried to do the direction to fix the problem you can find when you search for captions disappering but non of the works. The only way for me to get rid of it is to blow out my computer.

This does not only affect Premiere pro but also after affect (won't open) and photoshop is not working correctly. Do any one recognize this error/bug and know how to fix it?
