Program Error when adding video to Photoshop CC

I just learned that Photoshop CC is capable of video editing. I watched tutorials on Youtube to learn how to do it. I open the timeline and select create video timeline, then I drag a drop the video I want to edit, but instantly after dropping it I get a program error that says, "Could not complete your request because of a program error." It does not say why or what I should do about it. I tried adding a video that was in .wmv format and then another that was .mp4 format, and I got the same result both times. If, after I get the first program error, I try adding the video again, instead of a second program error, a message opens that says Photoshop is not responding, and I have to close it and start it again. I'm not very computer savvy, so I'm not sure how to interpret error logs, or even find them. Hopefully someone knows how to help!
