It is difficult to tell from the small segment of code shown, but it appears that the New File function is in a loop. Is it possible that the loop iterates quickly enough that it attempts to create the file twice with the same time? One way around this it to check first to see if the file exists. If it does, than append a 1 (or 2, or 3, or ...) to the filename and try again.
