Why won't an MP4 file load?

[Trudy Claspill]

What is the error message?

How big is the file?

Do you have the permissions required to add attachments?

[Julie Jungmann]

It was a sizing issue, I found it on another user's questions/answer. I've been able to add attachments of almost this size in the past, but I just split the video in two. Thanks.

And the error message was something along the lines of, reload and try again, and that the formatting may be incorrect.
