First impulse is this is an install problem if the File save options are dimmed. You made a screen recording, yes? If you saved the clip itself when the capture finished you will still have that to go back to. If you applied other elements or changes to it on the timeline, the fate of that is not known yet.
I don't find much on 1114 error other than it might be a DLL library error (sounds like an install problem to me). We really need to know the version of Camtasia you're using as well as your Windows operating system.
