Insrument missing when using green Apple Loop

Question

Greetings,
When dragging the green Apple Loop "Bread and Butter Bass 09" onto an audio instrument track in my arrange window, the result sounds very different than dragging the loop onto an audio track. When clicking on the "Bass" on the I/O of the channel strip of the instrument track, a small beige colored window pops up which says that it is the EXS24... which looks much different than the large green EXS24 (I presume the large green window is for the sampler and the other is not?).
Anyway, the EXS24 screen for bass says "MISSING: Thumbstroke Bass". Doing a search for Thumbstroke Bass reveals that there are three related files for this instrument on my system, and the file paths for each related file are as follows...
For Thumbstroke Bass.pst... Hardrive/Library/Application Support/GarageBand/Instrument Library/Plug-In Settings/Bass/Thumbstroke Bass.pst.
For Thumbstroke Bass.exs... Hardrive/Library/Application Support/GarageBand/Instrument/Library/Sampler/Sampler Instruments/Thumbstroke Bass.exs.
And for Thumbstroke Bass.cst... Hardrive/Library/Application Support/GarageBand/Instrument/Library/Track Settings/Software/Bass/Thumbstroke Bass.cst.
How can I get the green Apple Loop in my instrument track to sound similar to the way it sounds in the Loop Browser? If the problem is the missing instrument above (Thumbstroke Bass), then how can I get this instrument into my EXS24? Do all three files above need to be put into a special place?
I performed a scan update in my project manager... thinking that this would insert the necessary files into my EXS24, but I noticed no change in the menus on my EXS24 (the ? sampler too).
Thank you for the help...

Thanks to all for the very helpful responses.
Regarding Bee Jay's post...
The version of Logic that I am running is 7.2.3.
I recently added an extra internal hardrive (Seagate 500 gig, 7200 RPM) and installed the most up to date Tiger OS. I then installed Logic 7.01... a few weeks later, I upgraded Logic directly from 7.01 to 7.2.3 (bypassed 7.1).
In the process, I copied my garage band folder and portions of my Logic folder from my Seagate to my LaCie external hardrive with the goal of accessing instruments and samples from my LaCie. During recording, Logic is running on my Seagate, but the recording path records to my original hardrive. I noticed last night that the garage band folders on my LaCie and Seagate did not have the Thumbstroke Bass sample instrument files... whereas my original MacIntosh HD does have those files.
When installing the Tiger OS on my Seagate, I wanted to do a fresh clean install, and did not use Migration Assistant, and did not transfer any files from my MacIntosh HD which had Panther on it at the time. When updating to Tiger on the MacIntosh HD, I did a simple update preserving previous pref files, etc. (which explains perhaps why the Thumbstroke Bass files were not deleted on the MacIntosh HD).
I have some idea of some of the reasons this can happen.
The Garagaband instruments like "Bass", "Drums" and so on, are basically mini EXS24's. If you have a "Drums" instrument loaded, and load an EXS24 instead, the same instrument remains loaded and you can play it in the full EXS24 as normal.<<</div>
Yes, I have noticed the same above...
It turns out that there is a small amount of sample content that must be in a preset location - if it's not, Logic does not initialise any of the mini-EXS24's, and trying to load content that requires them will fail.<<</div>
Thank you, that makes sense.
My mini-EXS24's do seem to initialize, but they have the message "MISSING: Thumbstroke Bass". I presume that the small amount of sample content that *must" be in a preset location is not there... the question is... How do I get it there?
Try going to an instrument insert slot, and see which of the Garageband instruments you have available. In 7.1.x, there should be about 15 or so instruments - if you can only see about 9 or so, and can't see "Hybrid-basic" and so on, then this is an indication that you may have missing or moved Garageband content.<<</div>
My instrument slots show about 15 or so instruments under the Garageband instruments, and the "Hybrid-basic" is there. Should I be able to find "Thumbstroke Bass" in the instrument slot menu also? (so far, I have not been able to find it)
See my thread here for more details on this:

Have a look and see whether this might be the problem you are having.
If not, then get back to me, it might be a case of your sampler instruments or samples not being found.<<
Very helpful thread... I see some parallels to my current problem. You wrote that you had aliased your "entire AppSupport/Garageband library to an external drive, which works fine with Logic and Garageband except the sample based instruments in Logic - they seem to ignore the alias and hence can't locate the *.exs and/or the samples which they need." At the time, I did not know that I needed to create aliases, but I think that aliases were effectively created when I simply clicked and dragged the files from one drive to another, correct?
The next step that you wrote about puzzles me... You wrote, "So after a big of re-jigging the library files around, I've ended having the "Sampler -> Sampler Files -> Hybrid Synthesisers" samples and the instrument settings in the real AppSupport/GB directory, with all the rest of the samples and GB loops on the external drive." I am confused as to which files and their paths that you are referring to...
Don't forget that "Scan" in the Project manager does not change anything.<<</div>
I see!
I had forgotten that, and yes, it did not change anything.
In order to relink your files, you'll have to perform the "Resolve instruments" option, which goes and relinks sampler instruments with their required samples.<<</div>
THANKS!
However, after opening the Project Manager, I cannot find anything in the drop-down menus for "Resolve instruments". How do I get there? Do I need to do another scan to get there?
