Why these problems with one component?

Question

I'm going slowly and methodically but can't seem to get anywhere.
I am working from a backup copy of my Web site. I first tried creating a fresh copy from the DVD backup file. In that case, as in all cases, almost every page has a bad link bug. I thought I'd mechanically go through, it would be tedious but not difficult, and relink each questionable component, usually two per page.
That did not work. Whether I tried to relink the component that I could see, or whether I deleted it on a given page and added a new component object, then relinked, I'd get only blank component areas but no artwork.
I did notice that the Inspector kept listing the original file destination, call it xyz. This was the new file.
I tried recreating the artwork from prior versions and that did not work as it still sought xyz.
So finally I went back to the original xyz backup, relinked and the top component seemed to work. Not my ideal scenario but it worked.
That is, in Layout view it worked. In Preview it did not work and yielded this error message—
file://localhost [there it went through locations on my drive ending at] agl-tmp-1.html —then it added, "Could not open file."
After it did not work in Preview I went to PDF Preview, and that did work. So the problem so far appears to be with Preview for some reason. Perhaps that's a clue.
QUESTION ONE:
How can I relink that component so it works?
I would prefer to use the newer version and would like to outsmart that xyz destination in the object inspector if at all possible. So:
QUESTION TWO:
How do I do that?
I was hoping to resolve the relinking hassle today Monday and have the rest of the week to do the rest of the job but this initial hassle won't solve itself. Hope you can help. By the way, I need a Step 1 Step 2 approach not theory if at all possible. And thank you.

Answer 1

Nini,
First, thanks for the reply.
Second, your point about the Safari icons is reassuring. I will now set that aside as something I don't have to deal with.
Third, I do understand linking. But when I get the ? in the Links In/Out window, well, there I could use a little direction. The book I have, a Classroom in a Book, barely touches on that and my attempts have gotten me nowhere.
Last, about sitefiles. Maybe there is the core of my problem. Maybe it's "all my fault." I hope so because that is easy to fix once I know what to do. Here is what I did:
The backup of my Web site is a CD. I open GoLive and follow the procedure, New Site, Single User, and so on, and browse to that CD. There is no folder inside the CD that contains the files. There are the various files, roughly 2-300 and a handful of folders including the Images folder. I select the CD and the files all come in to the new site window. Somewhere in that process I have named the site.
Now I have a site window with all the files. And almost all the files have a bug.
I have experimented: Two graphic units, one a Component on top of most pages, and one a graphic element at the bottom linked within the Images folder, are the culprits. I do not relink those two items as the artwork has, somehow, disappeared, so I delete them. The top component leaves in its place the empty space that had contained the component element.
That deletes the two unlinked items that caused the bug, or so I thought. I notice that, while this page is open, the bug in the site window is now gone (hooray!) and is replaced by a checkmark. I save then close the page and the bug is suddenly back. The only problem that I can figure still remains, is one of the links with the ? in the Links In/Out (command-5) window. I know how to use the rubberband in the site window but I can't seem to do that in the In/Out window. Mostly the ? is on a file called Site Trash, if that's any help.
A lot of words but I was shooting for clarity.
Where is my error, if it's possible to tell?
Thank you very much.
