|You might be able to save "as an ISO" without purchase (you can on my old version of ISO Buster freebie). You can then create a new CD.|
Try copying the files onto your W98 HD then burning another CD using a different CD brand. Make sure you use a CD-R (not CD-RW) and Finalize it. Set the burn speed as low as possible.
With a bit of fiddling with drivers you could make a Flash Drive work on W98 and transfer them that way. I'd better not mention floppies LOL, it would take hours.
Have heart, if the CD is readable on W98 there is a way to get them to XP somehow (providing you can keep your hands on the machine). I work between W98SE, XP and Vista machines and have never been defeated yet.
