I have the same problem here! I can't submit the NETFILE error b/c of this error:
"The sum of capital gains before June 25 in box 52, and capital gains after June 24 in box 53, must equal the total capital gains in box 21. Review and adjust your entries."
Seeing so many people reporting the same problem most likely means I am not the one making numeric mistakes. It is pretty frustrating that I can't submit NETFILE at the last step.
