Patch problems - can't access CD

[hattie]

Help me!
I've looked at all the other topics about this but, me being a computer dummy, I don't understand how to fix the problems.
I've downloaded both patch and TTD (I'm on Windows XP) but whenever I try to get into anything it says "Can't access CD! $" or something like that and goes away.
I'm desperate to start playing. Can someone please post basic directions on how to fix this trouble? Win2k is ON and I've registered it (using regedt32) fine. Help!
Cheers
