Why has the entire configuration of my document changed?

I had used a series of images and lines to design my resume into something perfectly presentable.

But today when I open the file, none of the lines are where they should be and as a result I have an absolute mess of a document.

Why on earth has this happened? I want my file as I saved it. This is completely unacceptable and I demand that my work not be wasted.

It would help if you tell what kind of document (Writer, Calc etc) and in what format you saved the document - e.g. native Open Document Format, MS something or other.

How’s your graphic materail anchored? To page, to paragraph, as character?
