Help, Can't Publish Anything

[Gus]

No matter what I do I get the red X's on everything I try to publish. Everything was fine until yesterday. My suspicion is that this problem has something to do with the fact that I was working off my battery yesterday until my computer's battery went completely dead. Any ideas about what might be going wrong?

Did you leave those previous prints open in another app? If so AC can not print a file in such a case.
