Setting up home network... reload Hoster?

[70mlbu]

I am attempting to set up a home network so my business (Hoster) computer can get on the Internet. I think that somehow Hoster has seen the change in the business computers network connection and now says I have to reload the program. I've loaded about 80 discs so far and don't want to lose the data. Can I uninstall Hoster and reinstall it without losing my CD+Gs? And... what about registration? I haven't got the network thing figured out so won't be able to log on to register. Hmmm... I think I did that with a disc to get Hoster loaded initially...?

All I want to do is to be able to update Hoster files and WinXP on the business computer but as I mentioned... I haven't had much luck with the network yet.

Thanks for any help,
Dave
