Hiya, what may be worth doing then is finding the folder in which the original software was installed - probably something like C/Windows/program files/mp3player ?? and then manually delating all the files in that folder - once youve done that try and reinstall again - also worth checking is that the actual mp3 software is compatible with W98, some of the newer ones may not be compatible - which is why the driver cant be found - if you check the website of the manufacturer of your MP3 player,there may be some details there about it - or if you want to let us know what make it is, ill see if I can find any other information.
