PREMATURE, TAB PROBLEM, misspellings and not using provided photos for modeling

3 times now when I am typing a prompt the engine begins rendering simply because I pressed RETURN to TAB down in the wring of my prompt.  I do not feel I should be charged for this.  Maybe have a specific KEY to start the RENDERING.  

When I provide a photo I expect the engine to use the photo, NOT be inspired by it.  This work for a project and I cannot use aproximations or Inaccuracies.  Seriously, there MISPELLINGS in areas where I provide the exact spelling and layout and photo.  

What cinematic type animation can I use that creates with all of the important factors included correctly.  I am talking about about historical aircraft and not some fantasty world.  

I also should not have to pay when I have not said GO.  There is no way to stop.  No :05 delay, nothing; I would like to be credited. Why is it that every other type software I work with will ask me three times if I am sure that I want to do what I just said I wanted to do. 

Thank you,

Monty
