Way to bring back previously submitted forms

Hi there,

Recently i ran into this problem where cf7 updated and our form stopped working for about 3 weeks.

Is there any way we can retrive those form which was never sent?
I can even work with log file.

Reason why it stopped working was the change in naming convention for google captcha(the hidden tag). which i realize 3 weeks after it stopped working.

Any Help is great

Thanks
