IWeb will NOT open domain package, tried many things.

Question

I hope someone can help me. I searched the forum several times and went through all six pages of results looking for an answer. I did try everything listed in the few posts that did seem related, as well as a lot of those tips in combination with others, but nothing has helped.
Problem: After an AppleStore hard drive replacement, I copied things over from my Time Machine backup, as well as a backup of the more important things on another external drive. I copied things very peacemeal, basically starting from scratch for a few weeks to make sure the problem I was having was gone. (It's not, but that's a story for another day). When it came time to copy over my domain file and open it, it wouldn't open with iWeb. That is to say, doubleclicking it would open iWeb, but even watching activity monitor like a hawk, I couldn't see that it was doing anything.
Here is what I HAVE tried:
1 - deleted current domain file, and copied old one in it's place. No change.
2 - emptied the folder usually used to hold the domain, opened iWeb to create a new one. Close iWeb, copy domain to desktop, then copy the old one in it's place. No change.
3 - delete preferences and caches for iWeb, then repeat step 2. No change.
4 - delete preferences and caches for iWeb, then delete any combination of the following from the domain package: .plist files, domainstate.archive file, index.xml file. I tried this step about six times, with a different combination of these files each time, finishing with a repeat of step 2, and testing it. The only combinations that had any change were leaving only the index.xml file in the package, which got me about a second-long loading bar, then nothing, and leaving both the index.xml and the domainstate.archive in the package, which got iWeb to peak around 90-110% CPU (on activity monitor), flash the app not responding message a few times, then about 10 seconds later, it started idling again, nothing having opened.
Each time I've tried both opening iWeb first, and then actually doubleclicking the domain package. No difference between them. Then I copied the iWeb app from the time machine backup into my documents folder, and manually tried to open the domain package, with .plists missing, with that copy of iWeb. No change there either.
Both copies of iWeb, the one that last saved to the domain, and the one I'm trying to open it with, are the same version. I don't even been an OS update since it was last saved; I'm pretty sure I was on 10.6.4 then too.
I'm a little hung on what to do next. There isn't much in the domain package that could be causing issues except for the ones I tried copying out; everything else is just pretty standard file types.
That said, I'm not sure what could be causing the issue on the iWeb end, since I not only deleted the preferences and caches, but also tried a whole different application file.
I am planning to do a clean install on this computer, yet again, and start from scratch in hopes I can pinpoint what is causing my (unrelated to this issue) problem, for the Apple tech guys.
Should I just do another Time Machine backup with this new image, as well as keeping the old one, and then try to copy it over again when I've re-installed? I was hoping not to have to do it for another few weeks, because I'll need another external, since this one is out of space, but I also need to be able to edit this site!
Any help anyone has, even it's just a hunch of a suggestion, would be fantastic, and very appreciated. At this point, I'll try anything that won't damage any of my data, no matter how far-fetched.
Thanks!

It sounds as if the problems, or the symptoms at least, are the same. When I double click the domain file, iWeb opens (with the open/welcome/tutorial screen if I've just deleted preference and cache files), and I'll get the menu bar, but nothing else. With the right combination of files removed from the domain package (see my previous posts for that), I can coax a loading bar out of it, but it "loads" in the normal few seconds, and nothing displays. Nada. Menu bar has iWeb, but almost all of the items in any drop down menu are greyed out, all the important ones I checked for anyway, and you can see either the desktop or finder window, or whatever other application that was open before you clicked the domain file.
I'm not sure I included this in my last post, but I did try just simply disabling MobileMe, but without any luck. I never really thought it would work, but figured it could never hurt to try.
The disk utility found a few permissions problems, but none were related to iWeb, they all actually seemed to stem from one thing. I did repair, but no improvement. I'm hoping to have some time this weekend to try some different things to see if I can get it to open. I'll keep a detailed list of what seemed to help, what didn't, and if I'm lucky, what solved it. Short of that, free time allowing, I plan to do a clean install I need to do for another reason, on Sunday. Unfortunately that means you guys won't get any details as to what would have solved it short of something drastic like that (hopefully that will solve it...) but I've got deadlines approaching, not only for that, but for the initial reason for the clean install.
I will try everything I can think of, and anything anyone else can think of, and will volunteer to me. I'm going to move enough files around this evening and tomorrow on my externals to do a full time machine backup, plus second backup of the more important files, so anything you want to suggest, I'll be a testing ground, so others with the issue hopefully won't have to resort to the clean install. As re-installing iWeb had no effect, I'm going to assume, with my limited knowledge in this area, that problem stems from a shared file or the domain package itself. Hopefully not the latter; it's all I've got.
Anyway, if anyone has any suggestions of even something to look for that might serve to flag my attention to investigate further, I'd appreciate it, so we can get a solid plan of attack for others.
Thanks for your help so far, everyone!
