SpeedTouch USB/330 Software

Windows 98 is having trouble installing this software for our new NTL
broadbrand connection. Once the modem is recognised (and the green lights
show), the PC requests to restart and Windows locates new hardware and builds
the driver database, it then tries to install the software for it.

During this installation it requests for the Windows 98 Second Edition CD
Rom to be inserted, so it can find some files. This leads on to say it cannot
locate several files (10 in all) on the CD, which are needed to finish the
installation.

I have looked on this website and saw that downloading the 240075UP.exe
application (updated uhcd.sys - Fixes Problem with Some USB Devices Not
Running
). I have downloaded this file, yet I am receiving the same issues with the
Win98SE CD Rom not finding these 10 files needed to finish the installation.

What do I need to do?
Hope someone can help, as now I am offline and paying NTL money for nothing!
