The cd's you have are unfortunately extremely outdated and i would be surprised if anyone got them to run in all honesty,
the solution to this is to download the new client installer avaliable here
http://www.ryzom.com/newcomer/game-download
allow the patching process as normal and you should have no issues returning to game.
another thing to remember is to uninstall any previous versions of Ryzom and to delete instalation folders before installing the new version
