How to edit old articles?

[LSutherland]

I joined CC nearly 10 years ago but cannot see a way to edit some of my very old articles that didn't sell. I am keen to refresh the better ones and re-submit them. When I try to edit it only shows a percentage of the article (probably because I had the percentage set low at the time), but not the whole thing. There is no file attached either. Does anyone have any ideas? I cannot find the original copies on my system at home.
