Not sure how sure how Mr. Frost was helping the OP. Timbre4 is correct. Rants rarely get help... try it in a Government office and see how much help you get! :D
I am *GUESSING* the OP created a video and tried to produce it. After 3 hours nothing had been produced. I've had that with Camtasia and other applications. All were cleared up by either restarting or rebooting. Except the rare cases where the install was bad.
If that doesn't help, read Timbre4's comment or contact support.
Can we mute individuals? Edited to add, "it appears not".
