Search Tab in WebHelp Not Displaying Any Topics

Question

Let me preface this thread by saying that I JUST figured out the answer to my own problem. I tried to post this thread about 2 hours ago, but the forum was having issues...I got unexpected errors, and such. Although I figured out the answer a moment ago, I wanted to post the thread anyway, in case others come across the same problem, they will know how to fix it.
The Search tab in WebHelp doesn't work. No matter what I do, no topics will display when I enter search terms that I *know* are in the Help system. I have another project on the same computer, and the Search tab in that project works fine. I tried to attach screenshots, but keep getting an "unexpected error," so I gave up. But basically, if I enter a search term and click Go, "No topics found" displays.
When the WebHelp is being generated for this project, the following displays in the Output View:
"Processing Full-text-search data...
Finished processing Full-Text-Search data in 0 sec(s)"
It looks like something that is needed in order to do the full-text-search is missing, but I have no idea what. I have read several threads in the forums regarding Search tab issues that others have had.
I have:
    * Ensured that the itss.dll and itircl.dll are registered and in my C:\WINDOWS\system32 folder
    * Confirmed that I have keyhelp.ocx and hhctrl.ocx in my C:\WINDOWS\system32 folder
    * Used the same browser to view the WebHelp output for both projects (firefox 3.6.18)
    * Checked the project settings - they match
    * Checked everything in the WebHelp Settings window - General, Content Categories, Navigation, Search and Publish - everything matches in both projects
    * Tried creating a new webhelp layout, selecting a different skin...
everything, to no avail.
When the WebHelp is being generated for the project where the Search tab works, the following displays in the Output View:
"Processing Full-text-search data...
Finished processing Full-Text-Search data in 115 sec(s)
I can't understand why the Search tab works in one project, but not the other project. See the diagnostic report below. According to the report, the only thing I don't have (and don't know how to get) is MS Help 2. But why would my search work in one project and not the other, despite not having MS Help 2? Both project have the same settings and I'm generating the same output - WebHelp. Any ideas why my Search tab works in one project, but not my other project?
Thanks in advance for any assistance!

NOTE: In my original post, I forgot to include the diagnostic report that was produced by using the diagnostics tool mentioned in other threads where forum members were having problems with the Search tab, so here it is (just so that this thread is complete)...
MJ's Help Report
A common problem with HTML Help 1.x is DLLs not correctly registered during installation. This utility checks all components and registers DLLs if required. We also report if the RoboHelp DLL is registered, and if MS Help 2 components are installed and registered.
After running the report, try running your program again to see if the fault has cleared.
