Acrobat? CS? Illustrator? Photoshop? I haven't used Adobe products in anger for some years, but I can remember spending ages trying to match fonts so that line breaks and such matched up because some dimwit hadn't provided a set of fonts for a job. Fonts have long been an issue in repro, what with there being so many different versions from different type founders, so matching a font if it hasn't been supplied is a nightmare. I've still got a copy of my old font folder from ten or twelve years ago, and I had around three hundred fonts in there, many just different versions of one font, like Garamond, or Gill, for example.
Having older versions of whatever app you're using isn't going to help you any either, so I'm afraid you're going to have to bite the bullet on this one, grit your teeth and take it like a man!
