Strictly speaking, there is no way to /continue/ a /failed/ render: 
Whatever the reason was for failure, another attempt is pretty likely to 
fail for the very same reason.

+C only gives you a way to continue /aborted/ renders, i.e. where you 
said, "screw it, I don't have the patience for this today".

The mechanism is that when you abort a render preliminarily, POV-Ray (A) 
writes the output file as far as it got, and (B) dumps some internal 
state variables to a file, the name of which will be derived from (IIRC) 
the main scene file name (might be the output file name though, I'd have 
to look that up).

What you still need to make sure yourself when picking up the render 
again, is that (A) you use the same command line and INI file parameters 
(except for the +C and possibly radiosity and photons load/save 
options), and (B) the scene file parses the same as before.

If you're using the Start/End_Row options, essentially the same 
limitations will apply, or you'll risk a visible transition between the 
"old" and "new" portions of the resulting image. And you'll have more 
work to do.
